Howdy! Does anyone have or know of a guide to migrate from Listserv 17, including list archives, to Mailman 3?

I doubt there is one.

I've found documentation on moving to Mailman 2, but those don't seem to apply to the newer version.

There are about seven steps in the process:

1. Get the list configurations out of ListServ.
2. If separate from 1, get the user profiles and subscriptions out of ListServ.
3. Get the archives into mbox form.
4. Create the Mailman 3 lists.
5. Adapt ListServ configurations as much as possible to Mailman list attributes (there's not much you can do automatically unfortunately)..
6. Import the lists into Mailman.
7. Import the archives into HyperKitty.

Steps 1--3 are identical to the same steps for Mailman 2. Steps 4 and 7 are well-documented (eg, for importing from Mailman 2), and it doesn't matter what MLM you're importing from. Step 5 is manual labor. Step 6 I can't say much about until I've seen the result of step 5.
