I think the current license text already calls this out with this paragraph:

Maybe that could be improved by trying to point to all such different license terms in the tree - but as already mentioned, that has the downside of easily getting out-of-date.

However, maybe this whole point is an orthogonal discussion?
It seems to me that the github interface will just add a hyperlink to the license file, without trying to guess what the license is?

Maybe the only thing to be verified before landing this change is that every sub-directory has an identical LICENSE.TXT file to the one in the LLVM sub-directory? So that the one LICENSE.TXT in the root directory is identical to all LICENSE.TXT files in sub-directories. If so, maybe there would also be no use anymore for the LICENSE.TXT files in the first-level sub-directories?
