JouXIII wrote Had Sasuke NOT had Rinnegan, while making Susanoo, I doubt it would've been enough. Also, Black Zetsu itself had stated that it's probably because of Rinnegan that IT's light didn't penetrated Susanoo. His rinnegan made his Susanoo impenetrable, sure. What my point is, just because someone can make an Earth Wall to block a jutsu, doesn't mean they can tank it themselves. Just because Sasuke's Six-Paths Susanoo could block IT light, doesn't mean the Rinnegan itself is immune to the light, just that Sasuke can make a jutsu that is opaque to it. I mean, the Rinnegan makes the Six paths of pain jutsu immune to damage via Nakara but that doesn't make the user itself immune to damage.

IT light penetrated everything, except Susanoo. That means the Rinnegan has the ability to make jutsu impenetrable to the IT light, not that the eye itself is immune to all visual Genjutsu. Had Sasuke used Earth Wall, it probably would've stopped it too.
