Some wireless mice do work with some USB KVM's, so wireless may still
be an option.
Besides, Kensington makes a wired USB trackball.

So, that option exists as well. One just has to do a bit of looking.
I would recommend these as well.
I have used one for over a decade. Presently have 3 in the house and 1
at work.
Only issue that requires replacement of the trackball I have had is
losing one of the jewels that the track ball runs on. Found a place
that sells sapphire balls that are the same size to replace the lost
ones. Ball bearings from a bearing do not last long. You do need
sapphire or ruby.
My son broke his while gaming. It is very old and will need to be
replaced as I lost some of the parts from where it broke. Still working
with a bit of super glue.
The big ball is replaceable as well as the foam wrist rest at the base.
Micro-switches inside the trackball are cheap and easy to replace.
With some practice, I can do CAD drawings with mine.
The ball is 55mm in diameter.
I have not customized mine as I never really needed any changes from the
default.
