Lucas is more than likely not aware of the rumor and if he is he 100% does not care either way.
Lucas is not active on social media or holding daily press conferences...why would he feel the need to ?come out? and address every rumor that abounds?
The guy has not even publicly shared an opinion on the ST in spite of there being tons of rumors about his feelings about it.
He simply does not care and has moved on to a new chapter in his life...kind of the reason that he sold Lucasfilm to begin with...
Didn?t he suggest that the sale of Star Wars to Disney was like selling his children to white slavers ... I think he still cares about Star Wars. He also sold Star Wars together with his outlines to the ST on the understanding that these would be used for the Disney ST and Bob Iger pretty much admitted in his book that he and KK allowed Lucas to believe that to smooth through the sale. Iger also confirmed that George felt betrayed when his outlines weren?t used. I can?t recall if Iger said this, but it is known that Lucas did not like TFA because it didn?t bring anything new.
I would also bet that he is contractually obliged not to say anything negative about Disney Wars publicly for a number of years after the sale as it would affect the value of LucasFilm.
He was eager to come down to the set for Rogue One and the Mandalorian, not something you would do if you had washed your hands of the whole thing.
Oh he still cares.
