Yes, the ones I picked up are Torx.  They are new stock ordered from Motor
City Fastener.  They are actually readily available now since most fasteners
used in automotive are now metric standards.  Not all, but most.

Yes we do.  They have a low profile head that makes them easier to package.
Probably the biggest reason is for assembly.  They are easy to use with
automated equipment and the installation tool does not need to be larger in
diameter that the fastener.  Especially important with how tightly cars are
packaged these days.
