Black zetsu wondered if the Rinnegan made him immune. He didn't actually state it, nor did he name Rinnegan as the sole resistance to IT.

The entire argument falls apart if you consider that Edo Tensei are not caught in IT, so it's definitely within ordinary ninjutsu's reach to block IT.

Finally, considering you need the Juubi and the Rinnegan to end IT, it stands to reason that both can also block it. Nor does either give actual immunity: Sasuke's Susanoo was simply Opaque to the otherwise all-penetrating light. One can argue that if he used Earth Style he could create an earth dome that blocked it. Similarly, one can argue that Naruto could conceivably use a TSB sphere to block it. Of course, at that point Naruto had just sent them out and there was no time to explain.

Sasuke has only one Rinnegan, so it's also logical that if he was caught staring at the light, he would be put under IT. Therefore, it's strange to claim Rinnegan is immune to IT. It simply grants the tools to keep out the light, like welding goggle protect from the sun. Such goggles don't suddenly make your eyes immune to the sun.
