user3667: My goal is to create a transaction that spends dust outputs to a miner. Since the goal is to reduce the UTXO set by consuming low value outputs, I do not want to create any new UTXO by actually sending Bitcoin to an address.
Is it valid to make a transaction with several inputs and only one single, zero value prunable OP RETURN output?

user48884: Yes. Such transactions are valid and standard.
