I haven’t tried Haveno yet, but LocalMonero had an option called “Cash by mail”. It’s exactly what it sounds like: You mail cash to a Monero seller, and get your XMR in exchange. This is perfectly legal in the EU, it only might be an issue in the US, since mailing cash is technically not allowed by the postal service. Seems like Haveno also has this option: https://haveno.exchange/faq/#how-can-i-exchange-monero-for-fiat-without-involving-banks
