Split the code dealing with IR and not touching native llvm into a separate package not depending on native llvm.

>The llvmlite.ir module contains classes and utilities to build the LLVM intermediate representation (IR) of native functions.

>The provided APIs may sometimes look like LLVM’s C++ APIs, but they never call into LLVM, unless otherwise noted. Instead, they construct a pure Python representation of the IR.

Sounds like it can be possible.

Start by inspecting the llvmlite.ir module and separating the classes and utilities that construct pure Python LLVM IR from code that depends on native LLVM. Define the package boundary and verify that the IR functionality works without the native LLVM dependency; the issue does not name specific tests or files beyond this module.
