The big question on my mind when reading and considering this is, who is this aimed at? Is it aimed at casual players? Is this aimed at those who want to improve or that play competitively? If it's the latter I can't imagine it being of much help in the long term. It's better to understand why things are a certain way than to have an AI tell you to just do a thing. And unless you're playing at a high enough level already, things such as synergy or composition don't matter nearly as much as comfort with a character and their abilities. And as someone who has played games competitively in the past, I never wanted something to help me with things like awareness, along the lines of what the Valorant functionality displays. Keeping one's eyes on what's generally going on in the game has become much easier over the years anyway, to be completely honest.
I think for general strategy or builds in games like League of Legends or Dota 2, written guides and/or thinking for yourself will still easily trump an AI and will further one's actual understanding of the game and it's balance a lot as well. At the last Dota 2 International tournament a team won by their player picking up a rather unusual item that surprised even the fairly knowledgeable commentators. I think these sorts of AI or data based things just end up being a crutch for the players in the middle of the skill bracket but will fall off in effectiveness once they reach the higher levels where enemies will actually think for themselves and come up with counter strategies along the way.
Also has support for CS:GO actually been approved by Valve yet? I know they did some AI showcases at their events in the past but I feel like this sort of thing, unless very limited in functionality, will go against their stance on cheating.
