I would assume that there will be a neighbor who offers a money service to the village. He will have a Libra account. No need to drive to the next big city. Your family can go to that person who they trust and he will hand out the money.
And if it is not Facebook, it will be WeChat. Then you first have to send your Libra coins to a suitable exchange that will wire it to that neighbor.
Actually, many African countries have mobile money, so you won't wire it to a WeChat exchange but to a mobile money exchange [1].
