Extremely huge botting scene in coop vs ai games

I occasionally like to play some coop vs ai games either to finish dailies or while I watch things on the side as I find it quite relaxing, but I have noticed that this season in particular there has been a HUGE amount of bots being used by players to level accounts.

So many bots in fact, that it is actually quite rare to get a game where not at least 1 player is a bot, and this game for instance I had 4 bots with me today, which is not even the first time I have encountered 4 bots this season alone in one of my coop vs ai games.

Now had these bots been anything moderately well-programmed I'd have no issue, but they literally just feed and repeatedly die, making the game difficult to win if playing with 4 of them, and annoying when playing with others. But I also feel this becomes incredibly discouraging to newer players actually leveling and learning the game that I have from to time also run into as they get their task made that much more difficult and often don't even recognize that these are bots and not simply people feeding.

I am surprised that Riot has not done anything about this.

Are bots now okay to use for leveling accounts or is Riot simply not cracking down on them fast enough?
