If you are interested in writing tests for llvm/clang/lldb those
should be submitted upstream and not be part of the FreeBSD source
tree. Therefore, Kyua is almost certainly not the right solution.
https://www.llvm.org/docs/TestingGuide.html explains how to write
tests for LLVM, however, it is quite stale. I would suggest looking at
existing tests inside LLVM and adjusting those to match what you want
to test.

The FreeBSD src contrib/ import does not include the extensive LLVM
testsuite, so you could start by looking at
https://github.com/llvm/llvm-project/tree/main/clang/test for clang
and https://github.com/llvm/llvm-project/tree/main/lldb/test for LLDB.
I have never looked at the LLDB tests, but as far as I know there are
tests that use python to drive the interaction.
