recent josm versions also have built-in overpass download support - that
might save a bit of time when downloading with further refinements with
josm search.

That's currently the approach I'm taking

Running the overpass query looking for user DaveHansenTiger produced around
30mb of data. That's more than enough to keep everyone busy for a while.
Overpass-turbo query looking for user bot-mode produced over 100mb of data.
It would need to be refined some. As you suggest, looking only at version 2
might help but I'm not sure you can do that in overpass.

There is another way to tackle the problem, one that I've used as well.
Work on one county at a time. With 83 counties in Michigan the size of each
county should be reasonable for one or two people to tackle. You could
either break the county into small chucks using a Tasking Manager or just
work on one county by your self. JOSM search capabilities mirror overpass
so you can search for user and version.

I've done a fair amount of TIGER touch-up in Michigan, but there's still a
lot of work left to be done, and this looks like a great way to get a
handle on it. One issue: Due to the automated name expansion that was done
on untouched TIGER ways a few years ago (which I think only affected roads
in the eastern US?) a lot of these ways have bot-mode as their most recent
user, rather than DaveHansenTiger. (1)

The catch is that sometimes the name expansion changed the name after a
human mapper had edited the way, so it wouldn't always be valid right to
include ways where bot-mode is the most recent editor. (2) I think if
bot-mode is the most recent editor and the way has only two versions, then
it should be in effect an untouched TIGER way, but I'm not sure how to get
Overpass-turbo to pull that info out.

Any suggestions?
