Hi @Jeff Kirk,
Thank you for posting in this community.
We regret to inform you that there is no PowerShell command that can obtain the retention policy for each document library.
We can only view all the retention policies for that document library in Information Management Policy Settings.
Also, if you want to have separate retention policies for each of your document libraries, passing Information Management Policy Settings is a good way to do it. This setting only takes effect for the current document library.
Please accept my sincerely apologizes for any inconvenience this may cause. Thank you for your kind understanding.
