In Ubuntu some kodi addons are distributed as separate packages, including the default repo. See https://packages.ubuntu.com/search?suite=jammy&searchon=names&keywords=kodi.

There is a lot more you have to do, did you follow the instructions from both ppas? You need to download the mail firmware and rockchip compatible versions of chromium-browser, chromium-codecs-ffmpeg-extra, libv4l-rkmpp, v4l-util. You also need set up some udev rules etc.
