Itachi witnessed obito place nearly 20 people in genjutsu at once. This happened in itachi’ novel which is included on the canon timeline(s) hosted on this site. Also, Sasuke used basic 3 tomoe sharingan to read a life time of memories in an instant. You could argue that this ability scales to anyone with 3 tomoe sharingan, or you could argue that the ability is unique to his eye, but either way Itachi gets the feat because those are literally his eyes Sasuke used for it. Plus this feat happened in Sasuke’ novel which is just as canon.

Keep in mind that basic sharingan genjutsu can be placed in under 1/100 of a second, and ms genjutsu under 1/1000. This is also found in itachi’ novel.

Plus edo Itachi’ clash with bee and Naruto prove a strength and speed gap. Itachi not only exchanged blows with kcm Naruto, he also massively outpaced bee and Naruto while they were in mid swing. Knowing what edo’ mechanic is and how it works, alive Itachi’ stats are more impressive.

So even though yata mirror was nerfed to one directional here, it’s fine because he wouldn’t really need them.

Itachi makes a shadow clone that he sends to blitz and place them all in genjutsu at once. He then spawns totska and seals.

There’s also koto, shisui’ genjutsu, which proved effective against edo. So konan could wind up killing orochimaru. Or Itachi could just force orochimaru to undo the jutsu himself just like with sage kabuto.
