Preaching to the choir here. :-)  The problem is that we cannot rely on `libomptarget` to present for all possible configurations for the OpenMP runtime.  That's what this fragile thing has been invented for (not only for this functionality) but for all entry points into `libomptarget` that need to be present as a stub if the OpenMP runtime does not have offload support enabled.  To get rid of this, we would have to move the offload code even closer to the host OpenMP runtime, or split things up differently and enable the stubs only if the offload part is not present.  Something to discuss for 2026 in the LLVM OpenMP telcos.
