The assumption here is that you'd have a directory layout like the following:
|- LLDB.framework
|- Versions
|- A
|- LLDB
|- Python3.framework
|- Versions
|- 3.7
|- Python3
`Python3`'s install name is `@rpath/Python3.framework/Versions/3.7/Python3`, so
by adding `-rpath "@loader_path/../../.."` to `LLDB`, you make @labath's
request work:

The assumption, of course, is that LLDB is being built as a framework as well,
but I believe that's the standard setup on Darwin.
