Sasuke's rinnegan somehow allowed him to make his susanoo impenetrable by the light. That isnt evidence in any shape or form that the rinnegan is immune to visual genjutsu because Mugen Tsyukoyomi itself isnt a visual genjustu. The only people unaffected were edo tensi zombies, black zetsu attached to obito, and team 7. A visual genjutsu is a genjustu that alter's the targets 5 senses using their eyesight as the medium. Thats why its a common tactic to avoid looking at uchiha directly in their eyes. Itachi's finger genjutsu is a genjutsu cast by his finger when his target looks at it. Proof infinite tsyukoymi isn't visual genjutsu is that it trapped people across the world who were sleeping and werent looking at madara's eyes or the moon.

Itachi takes this battle 9 times out of 10. HE will lose occasionally due to stamina/tuberculosis issues and get caught off guard.
