You have no proof at all about the shockwave being chakra or not.

Kurama could've easily learned of Tenpenchii from Hagoromo.

You can be a jinchuriki with just chakra, or there wouldn't have been two seperate Kurama's existing. Minato sealed half of Kurama's chakra into himself and half into Naruto, and they both became jinchurikis.
