Deidara was caught in Sasuke's genjutsu being on limit himself, or he was just too proud in his victory to check the situation with the left eye again. Since he knows Itachi's speciality in genjutsu, he would be a way more cautious. Eye-contact genjutsu wouldn't work, and even if some non-visual techniques can succeed, Deidara can easily see through them if he'd realise that something is wrong. The only kind of genjutsu that probably would be useful is a sneaky one, like Sasuke's illusion on Danzo that briefly made him think he had one more eye for Izanagi. Regarding Tsukuyomi, it's something Deidara can easily avoid, since the close eye contact is necessary, whiel Deidara isn't so dumb to allow it. Amaterasu is avoidable as well, especially since Deidara almost always is a flying target (via clay birds) which isn't easy to hit with.

Yeah, the sacred weapons of Susanoo are dangerous, but only as long as Itachi can keep Susanoo active, and this time is limited. Even Yata Mirror cannot protect him from all the directions, something that is made worse by his Susanoo not having a lower body part, which makes him vunerable for underground attacks (Explosive Landmines, for example). Itachi is surely agile enough to avoid most of Sasori's attacks, but since Deidara would attack him at the same time, it turns into a damn hard deal for him, and even a scratch from Sasori's weapons would infect him with poison and means an immediate defeat. And I forgot, it's not only Susanoo, all the MS techniques have a heavy price, so he can't recklesly spam them.

I imagined something at once - for example, I see no way even for Itachi to deal with the combo of Iron Sand World Method, Explosive Landmines and C2 at the same time.
