Also Sasuke didnt say nature energy is effective against nature energy. Naruto theorized it and admitted that he didnt really know what he was talking about in that same panel

Ok, if Truth-Seeking Ball is not senjutsu, why did Naruto and Tobirama have idea to attack Obito with senjutsu?

Tobirama justified that idea with a toad attack. Because Obito couldn't neutralize it, it means senjutsu is effective.

But a little later Sasuke in a dialogue with Naruto confirms that only senjutsu is effective against senjutsu.

From this we conclude that Tobirama and Naruto had different reasons to attack with senjutsu? At the same time, Tobirama's conclusion was only about balls, but both attacked Obito's body.
