Yep, the case is closed. Your Itachi's fanboyism seems to be something that cannot be cured by reasonable means. Itachi is in no way perfect, by his own admission. Period.

P. S. No reason to believe YM can block sound genjutsu since it's never demonstrated such a feat. And Ao only said that Itachi can control usual people with genjutsu, not that he was controlling anyone and everyone.
