I am trying to link a list item to a report saved in a document library in a sub site.

Is this possible or should i move the document library to the hub page? (the list is in the hub page)

You can create a lookup column as a Site column from the list you want to refer in your site collection.

Then you will be able to add the newly created lookup column in your document library at subsite level.

Official Documentations:

  1. Create list relationships by using unique and lookup columns.
  2. Adding an existing site column to document library - Check the section "Add an existing site column to a SharePoint Online or SharePoint Server 2019 list or library"
