So I'm assuming that came from the novelisation of the Boruto movie.

Which is very questionable to begin with.

Correct. In the manga Sasuke says that Boruto added his chakra nature to the rasengan, but he didn’t specify which one.

The vanishing rasengan also had in both manga and movie that windy look to it, so i guess everybody assumed it was wind chakra.
