Can the RocksDB state backend used by Flink be queries from outside, e.g.
via SQL?

That's not possible, but you might be interested in queryable state: https://ci.apache.org/projects/flink/flink-docs-stable/dev/stream/state/queryable_state.html

Or maybe a better question, is there a RocksDB SinkFunction that exists?n

I'm afraid that doesn't exist, and it probably never will because usually RocksDB is not a distributed system so writing to it from a parallel stream processing application would most likely not work well.
