Bots and unresponsive playing

I have been trying to play Coop vs. AI to learn some new characters and while playing notice that there are MULTIPLE bots, every time I play! If I go mid, then there are usually two others that try to come with and never speak. Their actions/verbage are the same in every game and they will straight tower dive even when there is no chance at a champion kill or a tower kill. It is increasingly annoying because with players who don't play together, but fight on their own, lose us a game pretty fast.

How or what can be done to limit the Bots and get Coop vs. AI to be fun again!?
