Is there a way to apply retention policies to sub-sites in SharePoint Online? Something with PowerShell PnP where we list the sub-site URL and policy target in Excel?

We have looked at site collection policies from our farm admins, but we could have 30+ sub-sites under these site collections. To have 1 retention policy at the site collection level and force that on all 30+ sub-sites is a bit restrictive.

No, it's impossible. It's a limitation in Microsoft.
