You can use the /give command to create an item with a certain amount of durability by entering a damage value after the quantity. For example, to give a diamond pickaxe that has been used 50 times (1511 durability remaining), use this command:
/give @p diamond_pickaxe 1 50
The /give command also allows you to give items with NBT data, including the Unbreaking tag. To give a diamond pickaxe that will never break, use this command:
/give @p diamond_pickaxe 1 0 {Unbreakable:1}
If this is possible, the player who fired the arrow, either by UUID or by username, should be stored somewhere for each arrow.
First I checked the wiki for an arrow entity's NBT data. But as you said, while ThrownEnderpearl, ThrownExpBottle, ThrownPotion, and Snowball all have an ownerName field, Arrow does seem to have anything indicating it would store the player who fired it.
I fired an arrow and checked its NBT in game, as I've noticed the wiki occasionally misses out data tags:
But again there was nothing that stored my player ID. (Note that UUIDMost and UUIDLeast are both for identifying the entity itself, not who fired it)
I wanted to see if the data of who shot an arrow persists through the world closing and opening. To do this, I:
- Created a world
- Shot an arrow straight up
- Closed the world
- Opened the world
- Quickly opened the world to LAN
- Logged in with an account that was on survival, positioned directly below the arrow
When the arrow hit the survival player, not only was no ping sound played for hitting a player, but the message in chat simply showed that the player was shot by "Arrow", rather than me:
(Note that both players were logged on, the one that shot the arrow and the one that got hit by it)
Because of this, I believe that the player who fired an arrow is not actually stored anywhere in an arrow's data.
Thus the answer to "Is there any way to summon arrows that are shot by a player or mob?" unfortunately seems to simply be no.
I suspect death messages and ping sounds are done temporarily in code, rather than stored anywhere that can be manipulated with commands. They are lost when the world reloads, and are not stored anywhere in the individual arrow's data.

If it's not a problem, you can apply a speed debuff to armour through the use of attributes. If you do this, you can increase both the speed and the FOV with the Speed potion effect, then the attribute modifier on the boots will slow the player down. It'd take ages to tinker with and may have some odd consequences when jumping.
Just use this command as a base to start with to give the players boots, and play around with both the potency of the speed effect and the modifier on the boots.
/give @a minecraft:leather_boots 1 0 {AttributeModifiers:[{AttributeName:"generic.movementSpeed",Name:"speedDebuff",Slot:"feet",UUIDMost:1,UUIDLeast:1,Operation:1,Amount:-0.1}]}Change the
Amount:-0.1at the end. This currently modifies the players speed by -0.1, or -10% (they're the same thing).
