And again, you can't activate the Sharingan and Sharingan Genjutsu at the same time. The Sharingan has to be activated, then Genjutsu, that's how it works. It's Genjutsu is an application with the Sharingan being a computer; you can't run the application until the computer is on. Itachi needs to activate Sharingan first, and Minato is just the guy who'd be fast enough to react and look away

There's more time that Itachi used genjutsu at the start of the battle than not: 1. Against Naruto the time he fought Kakashi and Naruto

2. Against Naruto again when Naruto confronted Itachi solo.

3. Against Deidara

4. Against Sasuke

Itachi doesn't have to activate sharingan genjutsu and the sharingan at the same time. He can active the genjutsu right after he activates the sharingan. I honestly don't think it's realistic for Minato to react to Itachi activating the sharingan, it literally takes like a second.
