Cosmic Energy disrupts other energies, Chakra is composed of physical and spiritual energy. Cosmic Energy disrupts chakra by separating it into its components, meaning the chakra not belonging to the user is disrupted, which means that they are immune to genjutsu becuase their chakra cant be disrupted in any fashion.

"Despite its name, its actually not a dojutsu, as it comes from the body. Most users prefer to simply use it from the eyes, thus it is simply a bloodline limit, not a dojutsu, though by using it through the eyes, it will be an eye technique."

I have a few other kinks to work out but your questions are answered already.
