The Tri-chrome library is a library or a static file that is shipped with Vanadium, and gets updated with Vanadium updates. You'll find details of it in the Apps app > Vanadium.
I'm not sure which app you're seeing that window in, but best not to try to uninstall the Tri-chrome library. That said, even if you try, I don't think the app you're using will be able to uninstall it for you anyway.
