Even if you had 'ai tools' guessing at component blocks on evaluation you would have to have some evaluation of the result.
And, thats assuming NVDA hasn't pulled a Masatoshi Shima type play on their designs (i.e. complex traps that could require lots of analysis to determine if they are real or fake)
Im not sure how much of a speedup even modern tooling/workflow could do reliably.
Even then,
The elephant in the room is that China is working on their own AI accelerators/etc, so while there can be benefit from -studying- the existing designs, however I think they do not want to clone regardless.
