Looking online at the definition of debt, it is something owed by someone, or something that is promised in return for something given (paraphrased).
When you make a trade for a cryptocurrency (yes, shitcoins as well as bitcoin), you are owed a signed transaction and you can even define the number of confirmations you will require before you consider the debt paid.
You do not consider the miners or the validators as the recipients of your trade, so you cannot consider them your debtors.
For this reason, I would argue that cryptos are non-debt-instruments. Whether they are reliable instruments, and whether they are suitable to be given the title of "money" is where we see the difference between bitcoin and crypto.
No crypto, not even monero, can be considered trustless money, because they are not held to the same level of scrutiny as Bitcoin by their users, and how can they? They already diverged from consensus by ever being created and used as an alternative to Bitcoin, and the trustlessness comes from having maximum diversity in beliefs and thoughts participating in the consensus. Maximum, not "enough".
If you consider crypto to be money, then I would classify them as non-debt-money. It just doesn't mean it is good money.
