LS to send a giant flying?

[MintyBoi1]

I’m working on updating a characters Lifting Strength but the feat it’s based on is hard to get. What would the LS be for sending someone 11 feet tall flying a few meters back?

How was the giant launched? If it was a punch or blunt strike, I think that's an AP feat.

Just an attack, that could be why I only saw AP when looking up a reference though
