Sorry, I missed the second step - why would it need to get rid of the sed command?

I'd expect something like:

  ; RUN: sed -e 's/@/NUL/g' %s > %t.input
  ; RUN: llvm-tblgen %t.input | FileCheck
  
  Stuff @ more stuff

Oh, you mean the problem that the sed line itself would get replaced - then there'd be a null character in the RUN line? Maybe you can strip that off with `head -n +1` or something like that?
