I had not, but as I expected, setting prefix to my sandbox, I wound up with
everything installed inside my sandbox. In addition, the pylint command (as
well as others in $PWD/bin) still referenced #!/usr/local/bin/python3.9.

It's okay. I kind of thought I might be stuck. After all, I'm asking pip to
do something for which it wasn't designed. I was hoping I'd missed
something. (A --executable=/path/to/python/executable option would be nice.)
