Yet he only used it like what? Once? Not to mention it's abilities have never been elaborated on in great detail nor has it's origin. When he uses yata mirror to counter something else that is much stronger than Sasuke's kirin, then you can count the yata mirror. Besides, I recall it being White Zetsu that said that anyway, and even if Black Zetsu did say it, when characters refer to "all nature transformations" they always mean the five basic ones. The totsuka blade also has to impale it's targets, simply making contact with it wont suck them into the gourd and both of them are fast enough to avoid the blade and hit Itachi while going around the mirror.

As for the genjutsu thing, why would a sharingan genjutsu work on the rinnegan? You know how stupid that would be if a rinnegan user got taken out by a sharingan user with a simple glance when the rinnegan is the legendary true much more powerful origin of the sharingan? (Technically the Rinne Sharingan is but you know what I mean) But most importantly, it was never done, so we can't include it either way. If it was that easy to take down a rinnegan user with a sharingan genjutsu, it would have been done already.

All of those instances of Itachi putting those people in genjutsu don't count in this scenario. I don't remember when he put B in one, Kakashi isn't a Jinchuriki, when did he put Sasuke in it when he had EMS? Also, as for Naruto, Naruto didn't have a good relationship with Kurama at the time and they weren't friends, he was nowhere near mastering his power at the time, and what I mentioned involved all of the tailed beasts, not a single one.
