having a setting to globally turn off the Seen information (in group lists and anywhere else)?

I’m not sure about your actual question but this discussion relates to your issue:

Restrict public viewing of user profile

The concern in my community is that there is no option to restrict the “last post” or “joined” dates. Especially the first one can be a bit problematic - in our old forum software, one could choose to hide one’s online presence. Now, everyone can check when I last posted something online - even without registering.

It documents the setting that hides the user card:
