According to this datasheet (74LS154 Datasheet) the 74ls154 is supposed to run on 5v (+ .25 volts), but I tried running it off of 2 AAA batteries and it worked. How is this possible?

It's guaranteed to work between 4.75V and 5.25V. However, any given part will likely work well beyond that range, but I would not bet a consumer, commercial or medical product design on it as some will and some won't.
Okay, I see, thank you.

Speed would be the prime issue... Not as Fast.
