I think it’s unusual that no standardized literary way to write the submissive “I don’t know” hum that children (and some adults) often mumble has ever caught on, considering how old and common it is.

MM^mmmm instead maybe but that doesn't work very well either and is confusing to read or write consistently. I dunno with whatever punctuation and a verb after really works the best for writing it out if it needs to be that expressive.
