No matter a shinobi's 'level' if they have no skill in genjutsu how can they hope to overcome it? Jiraiya was an extremely high level shinobi yet had little skill in genjutsu. Itachi is also a far superior genjutsu user than Obito, he has tsukuyomi and has performed more higher ranking genjutsu. If someone suggested a way for Minato to counter any of Itachi's genjutsu I would call the match a close win for either of the two. Otherwise Itachi wins. Obito could control a Perfect Jinchuriki for years with Genjutsu, something that shouldn't be possible since they're supposed to be immune to genjutsu. Itachi's attempt to control a perfect Jinchuriki ended in failure (given how easily Gyuki recognized and broke it). Obito was the superior genjutsu user, and he only had one option against Minato: beat him in speed.

Jiraiya sucked at using genjutsu, but he had the defenses (high chakra control and high intelligence) to combat it. His method enabled Naruto to put up a defense against Itachi's genjutsu right at the start of Part II remember.

And finally Itachi wouldn't even be able to get a genjutsu off due to Minato's far superior speed with or without the Hiraishin.
