There's actually a chance that the anime will present Boruto's use of Kote during the Chunin Exams (during the Versus Momoshiki Arc adaptation) in another way that would explain why Boruto used it despite having enough sheer abilities on his own. As for now, it seems like he was just too lazy to use them while wielding Kote.
