GPUToolbox imported LLVM and LLVM.Interop without using either. The dependency only constrained which LLVM.jl versions the GPU back-ends can use: its compat entry has to be bumped for every breaking LLVM.jl release, such as 10.0, before any back-end can move to it.

GPUToolbox doesn't use LLVM.jl anymore: the
using LLVMlines were leftovers from when it was split out of CUDA.jl. The dependency still had a cost, though, since its compat entry had to be widened for every breaking LLVM.jl release before any of the GPU back-ends could upgrade. This removes it ahead of LLVM.jl 10 and bumps the version to 3.3.3.Tested on Julia 1.10 and 1.12, with no failures.
