Kiba also has Akamaru himself helping, Hana has three ninken themselves helping her, but is it considered two on one or four vs one when they fight? No! The ninken, despite having a brain, free will, seperate bodies, and sharing ideas and giving out warnings to their masters, are still considered merely as tools for the shinobi. In fact, Naruto even complained about this at the exams and he was told as much and had to accept it. Stop making up your own fanfictions rules, Kurama is a tool at Naruto's disposal, in the shinobi world, getting advise from Kurama is the same as reading a strategic warfare textbook or using a kunai. Those are the rules, plain and simple.
