I know rostopic hz /topic gives the total frequency, but can I get the frequency a particular node publishes to a topic?

Look into the topic statistics functionality. But note it does have its disadvantages / inaccuracies.

Not ideal, but you could replace that single publisher with a DiagnosedPublisher which publishes some statistics on a separate topic.
