Compiling from source is possible for most versions of LibreWolf, just head over to the relevant repository, clone it, and read the README.md. As LibreWolf is a community effort, people are trying out different things in different browser repositories. In general tho, most of the compilation issues come from creating the build environment, the actual compilation process by Firefox is standard and relatively straightforward.
brew install --cask librewolf
