We can't yet say they "do" rotate or anything else, because we can't
yet say they in fact exist; black holes, though they are on the old
conventional well-accepted end of speculation, are still speculation.
In all cases, though, they are not a "mathematical point" as you
describe. They have mass, charge, and angular momentum. In this
"normal" configuration, the singlularity is a point at the center of
the spherical mass. In this state, rotation is not sufficient to
produce any of the truly bizarre spatio-temporal effects claimed of
toroidial ones. There is also, of course, no model even in the realm
of speculation for any process that might create a toroidial or other
non-ideal black hole.
