So the backstory about this is that we are trying to give a reward out with of an enchanted book with a random level. Aka Protection I-V randomly. I know the command /give @p enchanted_book 1 0 {StoredEnchantments:[{id:34,lvl:X}]}, with X being the enchantment level, but is there a way to change that to a random number? Like random of the vanilla enchantments of course. Or do I need to explore scripts for that kind of stuff? Full story, Crazy Crates reward, of a random enchanted book, of a random level. Have the first two down easy, just the random level part…. Thank you ahead of time yall!

In more recent updates, you can see in advance what your enchantment will be (at least in part) AND it also randomizes after accepting an enchantment AND it allows the exchange to cherry pick enchantments.
By bringing a bunch of rubbish items to enchant in addition to your one diamond pickaxe will allow you to enchant the pickaxe only when it is silk touch. Via exchanging say an iron hoe with the pickaxe and lesser enchanting that instead will randomize again allowing you to try again with the pickaxe. Of course you would use levels to enchant the garbage items but doing lower enchantment will use less levels allowing for more tries.
So where you used to need 150/180 levels to try 6 diamond pickaxes you can look at dozens of tries for the same number of levels.
First note that the Enchanting page on the wiki says that Protection, Fire Protection, Blast Protection, and Projectile Protection are all mutually exclusive, but it looks like you can have Feather Falling on boots with one of the other enchantments.
The Armor page linked in the question has a table of "Enchantment Protection Factors" provided by each enchantment. I have duplicated the relevant parts of the table below:
Since increasing the level of the enchantment only increases the EPF, when trying to find the "best" protection it is only worth looking at the highest level enchantment. The article also says that in order to maximize protection from a particular kind of damage, you would need 25 points of protection for that damage type.
Since there are 3 different types of damage, one would need 75 effective points of protection, but since each armor can add either up to 11 points to one type of protection or 5 points to each type (which is like adding 15 total), the max is 60 effective points of protection. So, you can't max out everything. And plain Protection can't be maxed out at all. Therefore, the best armor depends on what you are looking for:
If you want to maximize the minimum protection value:
Put Protection IV on each piece of armor. This will give you 20 points in every type of protection. As a side bonus, if you put any level of Feather Falling on the boots, you will max out fall damage protection.
- Protection EPF: 20
- Fire EPF: 20
- Blast EPF: 20
- Projectile EPF: 20
- Feather Falling EPF: 38 (capped to 25)
If you want to maximize the average of protection values:
Again, put Protection IV on each piece of armor. Adding Protection IV to a piece of armor adds 5 to each protection type, so it adds 5 to the average. Adding any other protection enchantment adds at most 11/3<5 EPF on average.
- Protection EPF: 20
- Fire EPF: 20
- Blast EPF: 20
- Projectile EPF: 20
- Feather Falling EPF: 38 (capped to 25)
If you want to prioritize a particular protection type:
Plain old Protection:
Put Protection IV on all 4 pieces of armor.
- Protection EPF: 20
- Fire EPF: 20
- Blast EPF: 20
- Projectile EPF: 20
- Feather Falling EPF: 38 (capped to 25)
Projectile Protection then Blast Protection:
Put Projectile Protection IV on two pieces of armor, Blast Protection IV on one piece of armor, and Protection IV on the last piece of armor.
- Protection EPF: 5
- Fire EPF: 5
- Blast EPF: 16
- Projectile EPF: 27 (capped to 25)
- Feather Falling: 23
Projectile Protection, then Fire Protection:
Put Projectile Protection IV on two pieces of armor, Fire Protection IV on one piece of armor, and Protection IV on the last piece of armor.
- Protection EPF: 5
- Fire EPF: 14
- Blast EPF: 5
- Projectile EPF: 27 (capped to 25)
- Feather Falling: 23
Blast Protection then Projectile Protection:
Put Blast Protection IV on two pieces of armor, Projectile Protection IV on one piece of armor, and Protection IV on the last piece of armor.
- Protection EPF: 5
- Fire EPF: 5
- Blast EPF: 27 (capped to 25)
- Projectile EPF: 16
- Feather Falling: 23
Blast Protection then Fire Protection:
Put Blast Protection IV on two pieces of armor, Fire Protection IV on one piece of armor, and Protection IV on the last piece of armor.
- Protection EPF: 5
- Fire EPF: 14
- Blast EPF: 27 (capped to 25)
- Projectile EPF: 5
- Feather Falling: 23
Fire Protection, then the other two
Put Fire Protection IV on 2 pieces of armor and Protection IV on two pieces of armor.
- Protection EPF: 10
- Fire EPF: 28 (capped to 25)
- Blast EPF: 10
- Projectile EPF: 10
- Feather Falling: 28 (capped to 25)
Fire Protection then Projectile Protection:
Put Fire Protection IV on 3 pieces of armor and Projectile Protection IV on one piece of armor.
- Protection EPF: 10
- Fire EPF: 27 (capped to 25)
- Blast EPF: 0
- Projectile EPF: 11
- Feather Falling: 18
Fire Protection then Blast Protection:
Put Fire Protection IV on 3 pieces of armor and Blast Protection IV on one piece of armor.
- Protection EPF: 0
- Fire EPF: 27 (capped to 25)
- Blast EPF: 11
- Projectile EPF: 0
- Feather Falling: 18

Well i don't think you can, the closest thing to that would be different command blocks and changing them up every so often that way it randomizes, that or have them step on a pressure plate and the redstone signal going random directions, where the redstone sgnal would hit at different times, and when hitting one it ends up blocking the rest that way they don't get more than one, or use a dispenser....
