Nagato used the Rinnegan to put GENJUTSU blocks in all of Amegakure's citizens and ninjas brains. Rinnegan can cast genjutsu just going from that, but then again it wouldn't make sense for Madara to switch back to EMS to use Genjutsu like he did either maybe Nagato was already just really good at genjutsu idk
