VMS users can write or port all the compilers they want to.

 One of the following things would have to happen for that to be true:
 - VSI produces and makes available an LLVM developer kit
- VSI pushes back upstream everything people would need to develop compilers with LLVM
- People create their own port of LLVM for VMS

or:
- people use a different backend than LLVM (GCC, custom, whatever)
Regarding your last dash and my added dash:
No license problem.
No pure technical problem  either - getting LLVM or another backend
working on VMS is no harder than on one of the platforms where it
does happen.
Likelihood of it happening is probably less than winning powerball (west
side of Atlantic Ocean) / euromillions (east side of Atlantic Ocean)
3 times in a row.
The VMS community's interest in taking on open source work is
notoriously low.

As of today, the only way to get LLVM on VMS is to get a compiler
produced by VSI, and those compilers are not going to be
redistributable. I think VSI has expressed an intention to push their
changes back upstream but that hasn't happened yet and they have a
mountain of work to do to get there.

Yes.
