In german the usual saying in meetings is, literally translated „I can‘t say anything about that (optional: at the present moment)“.
That sentence is widely accepted as a substitute for „I don‘t know“, but at the same time doesn‘t hold the same conclusion, since there could be a myriad of reasons why you can‘t say anything about a topic.
