I installed it, after removing all other mods, I started the game, loaded an original map and played. All bots were the exact stupid ones as the original survivors. They watched me getting killed, all of them went by a molotov, none of them took it... I had a pipe bomb at the time, so it's not like "they didn't take the molotov so you can get it". No, they were simply stupid. All the original bot stupidity, from the original game. I put Left4Bots2 back and enjoyed real AI.
