Would I need to restart my current game if I enable the new DLCs? I'm not Byzantine but will the Legacy of Rome DLC screw up the Orthodox AI in my current game as France?
Someone please answer! I need to know!

It's very possible that it will create buggy behaviour. Either start a new game with the DLC or finish the current one without it.
Personally I don't see why it would. Major patches always risk making saved games buggy (1.06, 1.07 and probably in the future 1.09), but turning the DLC on or of should not matter much. Almost all of the stuff in a DLC is included in the corresponding patch, and buying the DLC just unlocks the new features and possibly also gives you some graphics or music.
