This is not a problem that RDAP is designed to solve. There are lots of reasons an RDAP server might not have info about a domain, e.g., you ask it about a TLD it doesn't handle, and there's no reason to assume that an RDAP server would know anything about an unknown domain's avaiability. It's true that you can't prevent clients from doing stupid things, but there's nothing new about that. If they keep hammering on you, rate limit or block them.
