Aubrey de Grey himself is also a computer scientist, who worked on AI before he switched to geroscience, so I would assume, that he is aware of the progress and the implications of the field of AI on research in general and longevity in particular. Whether other scientists in the longevity field are aware of the exponential progress in AI is hard to tell, but I doubt many are, when even a significant number of AI researchers themselves believe, that AGI is many, many decades away.

I personally don't think, that AI will be a necessity for the first generation of rejuvenation therapies, but will probably be essential in the development of next generation therapeutics afterwards. LEV is a long steady process, that will prolong our lifes with each generation by a decade or two, until we reach generation x, that will finally turn our bodies back into healthy, pristine twenty year old ones.
