The C2000 compiler accepts '-o<n>' or '--opt_level' to define the optimization level as well.

This overlaps with clang's -o <file> outfile specification, so there would need to be some sort of translation from TI's --output_file to clang's -o. Perhaps parsing the option would be enough, since there is no output from clangd?
