It looks like libva is designed to work without mesa (or other graphical stacks), since it's using libdrm to dispatch kernel calls.

There is also ebuild in Gentoo for libva do not depend on mesa (https://data.gpo.zugaina.org/gentoo/x11-libs/libva/libva-2.6.1.ebuild) or other graphical stacks (like nvidia-drivers or etc.).

I'll provide more information about actual problem that is happening in meta-kodi and it's related to this patch.

There is append that I created for meta-kodi, that is extending mesa with libva and libvdpau capabilities:

And this is current workaround for libva to avoid recursive dependency:
