That’s actually what hardware cheaters do (no need for the LLM part). They got a second computer, reading the screen, and a “MITM” device between the controller and the computer running the game to auto-aim.
No level of kernel anticheat can beat that.
They are talking about securing the inputs by basically adding tls beween the two of them, in order to make mitm a lot harder. A little bit more input lag, probably, but at least it will help defend agains prisoned USB devices.
