I hate writing the same thing a million times, scroll up and you will see. They have the frog song, which is leagues above Tayuya's genjutsu. And I also said that Orochimaru would take on Itachi, Tsunade would take on Sasuke, they will separate them while Jiraiya, Ma and Pa prepare, and then they will do the frog song.

I don't know where you get the idea that Genjutsu is useless on an Uchiha. Visual genjutsu yes, any other type of genjutsu would work on them.
