if certain knowledge has been made public, yes otherwise none.

AI's are trained on public (rarely on private ones - see below) datasets, which are usually sourced from the internet.
Lots of RE knowledge is kept secret and private.
(eg how to unpack ilok, remove the protection layer of Plugin Alliance, etc). Hence AI doesnt know about it.

Or for example how ilok in general works, chaptgpt isnt aware of it, since Pace never published anything about it. It only knows general stuff which you can read on the pace webpage.
And Pace wont do the favour and release their intellectual property to the public for AI to train on it. Instead they well use in house AI to improve their way of make it more difficult remove their protection.

I dont see that in general AI can be helpful for RE in the black zone.

Of course if you want to make your own research in coding, coming up with protections, AI can be of great help, simply because you have the source code to your own work.
