Some companies already do this with usage credits and/or time-limited plans. I think the problem with using Cashu (as is) for this is that you can't accept fiat and give out tokens that people can then convert to BTC on Lightning through your server without becoming an unlicensed exchange. It would have to be utility tokens that are only spendable for your own service to avoid this, no?

(Sorry if I missed that this is the idea and that it's already easy to do like that.)
The ecash would never leave you as a service provider from what I understand.
But you then need to be able to prove that the ecash is only used for your products/services.
If you don't run a gateway yourself, I think that should be fine. People trading your utility tokens p2p is not your problem as a service provider.
Fun fact: this is actually how mobile money like M-Pesa started: people used airtime for mobile networks as a currency, then the carriers saw this and turned it into e-money products.
Spot on re: Mpesa
funny that it’s only a few years ago when Mpesa went fully KYC and since then it’s become a privacy mess + big honey pot for hackers
eCash is a good case study on how to rebuild Mpesa the right way.
