[Bioshock Infinite] Do WWI and WWII still happen in this universe or is the timeline too different?

Probably. There isn't any mention of it, but Columbia isolated itself from the rest of the world after declaring independence, and in any case the USA wasn't part of the war at that time.

Having said that, it's entirely possible that the First World War didn't happen in one of the universes you shift into during the course of the game.
