Chesky, if we trust your testimony, then what are we to of R Landau’s position that R Chaim did not hear the right question (or of posters who say that video is AI-produced?). Was now he mislead?
It seems that you hold that we can rely on gedolim to produce correct thinking subject to input they get. There are probably some gedolim who agree with that. for example, R Eliyashiv admitted that “I am not a navi” with confronted with information that was withheld from him.
I think the simplest resolution would be for someone to respectfully deliver this additional info to R Landau and R Feldman and to see how they respond. If it is not possible to get this information to a Rav, that would also be useful info. Any takers here close any of them?
Of course, you can simply point to the kol koreh that publicly admitted that there are Talmidei Chachamim who have an opposite opinion, although they did not quote them the way Beis Hillel would.
