Kishimoto explicitly didn't want to revive Jiraiya in the 4th war. Why would he ever greenlight that idea now? Makes no sense. KK is not Jiraiya. Related, perhaps (Jiraiya traveled the world and liked "research", so there's no telling if he left any kids), but not actually  Jiraiya.

People can extinguish chakra. Both Muu and Karin could completely erase their presence from Sensors. Don't see why KK couldn't do the same.
