First, I wanted to remind you that the message archive does not count against your storage capacity in Groups.io.

It is difficult to bulk delete messages from the message archive.

The Help tells you a bit about deleting topics and individual messages.
/helpcenter/ownersmanual/1/managing-group-topics-and-messages/deleting-topics?single=true

I have moved messages into topics and put a timed delete hashtag on them. But I haven't tried it for years of messages.
