Not really sure about harder. If you avoid pipes (by writing the output/input to temp files using lit's shell-test `%t` substitution) and use files instead tests should still be easy top debug.
Apart from the architecture not being very clean with `-lit-test` the biggest problem is that if your tests always use `-lit-test` it means you're never actually testing `clangd` in the configuration
it's actually going to be used in during deployment. To me that seems completely unacceptable if you actually want to have confidence that the code that is deployed actually works.
