My guess is that they differed quite a bit from Chicago way back when.
I can do some research into that if necessary, but first:

If I understand you correctly, people in Wisconsin actually keep their
clocks according to the federal rules, but once a year the police hand
out tickets as if the clocks switched at 01:00 rather than at 02:00.

If that's the case, then there isn't a need for a change to the tz
database proper, as our usual practice is to record the time that
people actually use.  But thanks for the legal citation and remarks:
I'll add a comment.
