Is there a way to know that a document or a sharepoint site is related to an Archived Teams?

Hi @davcano ,
Unfortunately, there is no way to know it in the sharepoint site, because this function is to work in teams, and this can only be known in teams.
Please read the link below: https://support.microsoft.com/en-us/office/create-a-microsoft-team-from-sharepoint-545973b6-c38f-426a-b2b6-16405a561628
Add real-time chat, virtual meeting capabilities, and extended collaboration features to your SharePoint team site by adding Microsoft Teams.Learn how to link sharepoint to teams in order to realize real-time chat and document collaboration in Teams. Then archive a team when it’s no longer active, but you want to keep it around for reference or to reactivate in the future. The conversations and files in the team become read-only once you archive it. You’ll still be able to search through it for stuff you need.

This function is to facilitate access to sharepoint resources in Teams.
You can see that documents of this Teams or SharePoint site of this Teams are related to an Archived Teams in Teams, not in sharepoint site.
