Yeah it reacts with water, but if it is damaged it also reacts with itself and the air around it anyways. Adding water still cools it which slows the reaction rate and reduces overall fire temperature. Once a lithium battery lights on fire there really isn't much you can do to actually stop it, you just want to suppress it and keep it from damaging or lighting other things nearby on fire.
