So Chaos is a really neat passive item that causes future items to be chosen from random item pools. Basically that means any item can appear anywhere at anytime until that specific item pool is depleted.
I'm wondering if it's worth buying Chaos when it shows up in Greed Mode. Greed Mode's items already seem to be pulled randomly from item pools. For example, items that show up only in an angel or devil room in the main game are often available in the Greed Mode shops. So is it worth spending money to buy Chaos in Greed Mode? Does it actually do anything?

As said in the answer of pinckerman: It depends.
The good
The bad
So in the end it depends on what your goals are for the run. Do you want to play it safe and be assured that you'll keep finding hp items (since the boss room pool contains a lot of them)? Don't take it. Do you already have a way to infinite money? Take it, it'll help you get even more offensive items. Do you need that final guppy item? Take it if you like a gamble.
I personally always take it because I love the randomness, but it's up to you and your current situation. On a small note: do keep in mind that breaking the game and buying half a million items makes the game crash quite a lot, especially when you actually end up in combat. I had one run where I could fire one shot in the greed combat room, and then had to wait until everything was dead or my shot had subsided from being everywhere. Firing a second shot would crash the game. But at that point one shot would clear at least three or four waves.
