Just downloaded BioShock 1 Remastered on my deck and launched it in offline mode, works fine! No launcher even without any arguments, maybe they disabled it on Linux due to the issues.

I assume it’ll be the same for the other two.

A couple of options worth knowing about since I don’t know/own the games:

1. A DRM free version looks like it’s available at GOG. This is probably the simplest solution to not have to worry about any potential issues
2. People seem to be reporting that the Steam version can be launched directly from the executable bypassing the launcher. If there is a Steamworks DRM check you could always use Goldberg’s steam emulator to get around that for fully offline play.

You could always purchase the collection then refund it within the return window if it doesn’t work as you like.
