Actually libass 0.15.1 was released this weekend, a pr for bumping the version is already in the queue for v20: https://github.com/xbmc/xbmc/pull/19672
Since you're running Linux, Kodi uses system libass so as long as you update libass on the host you can use that without any change/update to Kodi.
