That would mean avoiding eye contact, IIRC only Gai and Kakashi can do that while having to keep with his movements that even proficient Sharingan masters had some trouble following.

Excluding Sage Mode nothing he can do will surprise Itachi since he is slower than him and he benefits from the heightened perception granted by the dojutsu including predicting movements, seeing chakra and facilitating genjutsu.

According to Ao, Itachi has long range genjutsu outside of even a sensor's range

Summons and such can be placed in illusions as demonstrated by Sasuke, Madara and Tobi.

Kakashi made it clear that you cannot cancel Tsukyomi.
