Whether or not TSBs have natural energy is unclear. Naruto definitely implies they are, as that's his explanation for why Gamakichi's Senjutsu technique wasn't destroyed by the TSBs. We know for sure Obito had natural energy through Six Paths chakra, and Naruto and Tobirama both directly infer that, because Kichi's technique wasn't erased, that Senjutsu techniques work on the Juubi Jinchuriki too This implies the TSBs have Senjutsu chakra in them like their caster. Possibly the databook just made an oversight, it happens (for example, it forgot to list Danzo as having a Summon).
