I would still like to see a picture. If that messenger is truly "not
connected to anything" (not bonded) it is a NESC violation and a
safety hazard, no lineman would allow to happen.since they are the
ones who are in danger,

I bet that when we actually look at it we find it is crimped onto the
strand between poles where everything else is bonded. There won't
usually be a direct connection to the transformer and maybe that was
the confusion.
And no connection at the building, in all likelihood.
