From the command line, the following command will give you a list of all authors who have made local-only commits to a branch `some-branch`:

    git log some-branch --not --remotes --format="%an"

And to get a clean list of branches suitable for scripting:

    git branch --format="%(refname:short)"

If you are working in a Bash-compatible shell (which you are if you're on macOS or Linux, in all likelihood), you can use these to make a scriptlet that prints every branch which doesn't have any local-only commits not authored by some set of names:

    for b in $(git branch --format="%(refname:short)")
    do git log "$b" --not --remotes --format="%an" | grep -qvE 'Jane Doe|Bobby Tables' || echo "$b"
    done

(Note that this may include branches that don't have any local-only commits at all! But those are probably also decent candidates for deletion.)
