Braiins or OCEAN are your optiins for small lightning payouts.

Braiins is the most simple, since you just have to give them a lightning address.

OCEAN is more involved, since you have to sign a message using the private key for the Bitcoin address you gave them. However, this is because their accountless model is better overall. But then, not all wallets support BOLT-12. Coinos is a good option in that department.
