What is the best tactic when you have a young kingdom, just opened up and a 150 billion player comes in and is a real #$%# . Big tough guy picking on 20 million power players.
Shield.
Zero else you can do.
* I will also suggest you click Menu, in game, then help, and follow those steps. This 150B seems pretty blatant and counter to what they intend, given your kingdom's age. I have seen no reports here that they will do anything about it, but it does seem from your post that the size and age are edge cases beyond the characteristics of anything I've seen reported.
