When a content object is deleted, signals/events are sent which can be intercepted to remove relevant tags.
As part of #79, openedx/openedx-platform#32907 implemented handlers that receive event signals for when various types of content are deleted, so that the content tags associated with the deleted content object can also be deleted.
These signals were demonstrated to work for deleting XBlocks, content libraries, and content library blocks.
However, the signals for deleting course blocks don't seem to be working, and so content tags applied at the course level are not deleted.
Since "course level content tagging" isn't supported by MVP, this is something that should be fixed as part of a subsequent project phase.
