Airdrops are all luck these days, and if it wasn't luck they would not be rewarding as they are. Zksync, layerzero could be having a token but due to super high speculation on those, even if they do have a retro airdrop, they will be having strict requirements.

Interacting with those protocols will require good amount of $ to be spent, and then again it doesn't guarantee anything. Best suggestion I can give is interact with dapps/protocols where you feel like doing so and leave rest.
