If we do hit the inline rescue would this code not just re-raise that error, instead of the initial AnsibleTowerClient::Error that we really want to raise?

I think this is more what you want:

rescue AnsibleTowerClient::Error => err
  begin
    raise JSON.parse(err.message).values.flatten.join(", ")
  rescue JSON::ParserError
    raise err
  end
end
