LLVM would have been created even if free/open source, SubstrateVM style tech existed back then because LLVM was designed as a competitor to GCC for compiling C and C++. The JVM can run C/C++ code these days 'natively' (by JIT compiling LLVM bitcode using Sulong) but that's not what it was created to do. Also bear in mind LLVM is not really a JVM competitor despite the name. LLVM is a toolkit for building compilers, primarily, C/C++ compilers. Other languages that targeted it have had to do a lot of work to change LLVM for that language. It's not actually a "VM" in the JVM or V8 sense, for instance, it doesn't provide a garbage collector and LLVM bitcode is neither platform neutral nor a stable format.
