Totsuka Blade is avoidable, Yata Mirror is not omnidirectional, Susanoo doesn't last long, Minato can teleport it away, Amaterasu is avoidable, Minato is faster physically than Itachi so he isn't only limited to his kunai, Gamabunta and friends keep Itachi occupied while Minato looks for openings or seals Amaterasu (his sealing prowess seems much more potent than Jiraiya's so it shouldn't take him too long), and Itachi eventually runs out of steam.

I think Minato will win. But either way it goes, it'll be a very hard fight.
