There is absolutely no reason to suggest, aside from Infinite Tsukuyomi (which appears to be a special case, only a Rinnegan wielder can stop it), that perfect Jinchuriki are incapable of breaking those Genjutsu. In fact, considering Ao could recognize when Kotoamatsukami was being cast, and that the Jutsu does not prevent the user from finding out they've been affected by it and changing their mind, it's nearly certain the Biju would notice it and be able to end it. Tsukuyomi is not unbreakable in any case, it's a Genjutsu in the end.
