Confused! How to report bots or am I just unaware of something...

I am almost certain they are bots in these co-op vs. AI games I am in. Learning the game and playing in these types of matches have been good for me and I have been lucky to get helpful players to give me insight and information on how to play better. That being said, it is usually just three of us. The other two run straight in the middle to attack anything in their way to die either on tower as it lights them up or a champion under a tower where both light them up. It is annoying and causes us to scramble about. I know its just a bot game but it takes away from my learning experience as it becomes a jumbled mess.

I guess the short version of my question is: how do I report this? I cannot find a 'bot' section or are they not bots and just people bored and wanting to experience the feeling of death by tower? Without the lack of a bot section should I report them in another way? Thanks for any input anyone has! :)
