Well, Kakashi knew about Tsukuyomi from nowhere so we should expect the same from Minato, Amaterasu is already gone,Susanoo is a competent but chakra and eyesight draining defense so that just leaves Itachi's normal genjutsu, now first of all, I've never heard the whole someone is needed to help you break every sharingan genjutsu, Naruto wiki didnt mention that either, Sharingan genjutsu is given any special treatment only mangekyo sharingan genjutsu is, Deidara broke Sasuke's sharingan genjutsu by 'training his eye' did Kishimoto forget that? In any case, all of Itachi's genjutsu are short range if you check them all so Minato needs just keep his distance and throw his kunai, closing the distance only to instantaneously attack or summon toads the size of Gamakichi in part 1 to help him break genjutsu, these are tactics he would have to use if he cant just normally break the sharingan genjutsu the normal way as must have been taught to him by Jiraiya or the pain way which even Shikamaru as a genin knows and has never failed to break a genjutsu. Also the fact that one can manipulate chakra to break a genjutsu means that one can use techniques when caught in a genjutsu as evidenced by Deidara almost bowing himself up and Orochimaru moving his hands to break the genjutsu Itachi cast on him so Minato can teleport to safety which will completely erase his chakra and relocate him a good distance from Itachi's range of genjutsu.Undoubtedly Itachi's strongest Genjutsu are based on the Sharingan. But even those strong ilussions don't always require eye contact. Magen: Kasegui, the Genjutsu he used to defeat Orochimaru, the one that impales the enemy, doesn't need eye contact. That's a 100% proved, since that's how Kishi said it in the Scrolls of Sha. There's also a small part about Genjutsu and how to cancel them. It's written there that a second person is necessary to cancel a Genjutsu based on the Sharingan. Those aren't just normal ilussions. There's a reason why Kakashi said that fighting someone like him one on one is impossible. I mean, how should Minato be able to cancel an ilussion if he's paralyzed and unable to form seals?
Anyway I don't see how he's supposed to dodge Amaterasu either. If Itachi seriously intends to kill Minato, he'll doubtlessly use Tsukuyomi the moment Minato looks into his eyes. You're talking about avoiding eye contact. But how should Minato know about Tsukuyomi? It's totally normal to look into the enemy's eyes. Even if he would be aware of it, eye contact can happen at any time, even if not intended. Even if he somehow would manage it to dodge it; Itachi could simply use a small ilussion to make his Amaterasu unseen the instand it can be seen. Like Madara said, the trick lies in how to use even a small, weak Genjutsu.
Even if Minato could, however, avoid both Itachis Genjutsu & his Amaterasu, I don't see what he intends to do against Susanoo.
