Yeah, most of the genjutsu is ineffective against Junchuriki, cause they have their TB inside, which can pull them out from it, but I'm sure at least Itachi's Tsukuyomi would be very dangerous for them, it has nearly instant effect due to it's ability to alter victim's time perception, as you know, TB just wouldn't be able to dispell it in time.

Besides, we don't know much about some of Jinch's ammount of control over their TB when alive, so it's hard to judge how powerfull would be, for example, Han or Fuu.
