Before we installed the new license, that is the scheme that we had, see e.g. https://github.com/llvm/llvm-project/blob/eb60fbfdb43cb8583eda1e338b3489ddef332f10/llvm/LICENSE.TXT for what the license file looked like for the llvm sub-directory. You can see that at the end of the license file there is a list of directories that contains differently licensed code.

When we still had that scheme in the LICENSE files, when people asked me what licenses were in an LLVM binary, I pointed to the combined list of directories in those LICENSE files. But also stated that there was no absolute guarantee that they were perfectly kept up to date. Based on that experience, I'd say that just mentioning that there are directories or files with a different license + how you can find them would be good enough, rather than trying to keep the list of directories up to date.
I'm also not opposed to explicitly listing the directories/files in the LICENSE file, i.e. doing what we did before by listing the directories with different licenses - assuming we also somehow state that the list is kept up-to-date based on "best efforts", rather than guaranteed to always be fully correct.
