For mainnet there will be a fee to create a shared key (i.e. deposit a coin) which can be paid via LN. After that all transfers are free.
This is similar to an opendime, where you buy the device initially and then all other use is free.

Someone could do that (direct from fiat with the fee included). Not sure who could offer that without KYC though.
