If they had never left the country, they'd still be in the US so the child would have citizenship from place of birth. If the mother grew up in the US but left before reaching the age of 19, the child would indeed not have US citizenship - like Winston Churchill, as it happens, whose mother was born in New York. (He was the first to be awarded honorary US citizenship, in 1963, but didn't inherit it from his American mother.)
