Is it normal for the "low coolant" light to be on after the TB bypass? I just did the TB bypass mod, and now my "low coolant" light comes on periodically. Is this a normal occurrence?

Assuming this is an fbody and the system isn't actually low, check the sensor on the passenger side of the radiator. You can replace it or just unplug it. I'm pretty sure unplugging it is what I did to get rid of the indicator.

Well when I removed the hoses from my TB, quite a bit of coolant came out of the TB itself. Could that cause it? Also, if i DO have an airpocket in my system or w/e, then how do i get rid of it?

Air shouldn't cause that light to come on. Check the fluid level. Don't trust the dummy light. If it's low, fill it. If its not, its the sensor. Unplug it or buy a new one.

after you check the coolant level, start the car when its cold, with the radiator cap off. run it until its warm. That should bleed off any trapped air. be careful that the radiator doesnt overflow from the level rising as it heats up.
