[BUG] Crazy things happen in Co-Op vs Bots

So this master yi started the game and the first thing he did was go towards enemy bottom turret and die. Its not like i care that he fed enemy bots, but i have seen this happen before and its usually a soraka. This Master Yi also was saying the same things over and over again. I dont think its a player. I think its a computer playing or something. Could you look into the matter? I repeat that this usually happens with soraka. I saw a soraka like this today and when i got in the champion select she had already locked her pick. And it was like unbelievably fast for a normal player. I dont really mind, but sometimes its annoying.
