Yes, our benevolent government wants to protect us by now allowing any of these apps like Strike, Venmo, etc. lol
Would you be against using coinbase? You can just buy there and immediately send out via lightning
For non KYC use robosats, If your not concerned about KYC you can use Bull Bitcoin, transfer fiat to Bull Bitcoin account and they support lightning so your buy will be set directly to you Lightning wallet they do not custody funds so all purchases either on chain or lightning require a receiving address. On second thought Kraken supports lightning too and they have lower fees/spread them Bill Bitcoin. But Bull is Bitcoin only and doesn’t custody so chose your poison I guess 🤷♂️
