As these tools advance, their opinions will converge, and they'll have similar opinions of what equilibrium play is. Even elite players are not going to play inside-equilibrium-support more than ~80-90% of the time, and even when they play inside-equilibrium-support, they're not going to mix with the same frequencies as the bot suggests. I think looking at any one game and saying someone used outside assistance is never going to be feasible, but I think statistical analysis of many games of a player will be able to tell you, with high likelihood, who is consulting a bot. In endgames, my bot can often effectively solve the game, and even measure how large a blunder any off-equilibrium play is. High ladder opponents still regularly make endgame blunders, and a total lack of them is suspicious.
FWIW the same is true both in chess and poker. In all but the most outrageous cases, you cannot tell engines were used in a single chess game, but collections of games can give a statistical signature. It's even more true in poker.
I intentionally chose VGC for this particular reason. I don't think detection is as hopeless as you seem to think it is.
I'm happy to engage with you in good faith about how the community should react to the advent of these tools. I would ask that you lower the temperate a little bit with respect to statements like "In the creation of these bots, you do destroy an entire community of pretty much the entire 6v6 community". I think that statement is both inaccurate as to the outcome of the creation of these bots, and personalised/pointed towards me as an individual. I am doing what I can to help the community take the advent of these tools seriously.
People airing their legitimate concern about the integrity of the game is totally reasonable, but I'm trying to engage with the people who are looking for solutions.
