Any technique stemming from the eye is a Dojutsu, and because the eye is a visual organ, that makes Koto a visual genjutsu. Because the Rinnegan is immune to all visual genjutsu, it will not affect Nagato.

That information is not true, it was fabricated by some random people who just said that Nagato's databook article says that. But that's not true. But the Rinnegan has never once been depicted being affected by visual genjutsu at any point in the series. A Sharingan genjutsu being able to affect Rinnegan, it's true and more evolved form would be ridiculous anyway. But based on what we've seen, the Rinnegan has never been caught in visual genjutsu and no Sharingan user bothered to ever try genjutsu on the Rinnegan. So it's plausible to assume that it doesn't work on it.
