I believe so - in just about any state. The point being that the baby, no matter what the circumstances of the conception, does have a father. There was a case some years ago where an underage boy was given oral sex by a woman using a condom who subsequently used the contents to get herself pregnant. Even in that case, the boy was listed as the father with all the responsiblities that entails.
It's a tought situation - one way or the other, someone gets screwed. Legally, I believe they decided that it was more important that a baby whose father whose paternity was known be responsible for that child, than try to adjudicate the extremely rare cases where the father is completely not responsible for impregnating the mother. Rare cases make bad law and all that...
It also seems to me that if the boys are responsible for child support, wouldn't they be able to file a civil suit against the mother for putting them in that position? Haven't heard of this happening, but it makes sense to me given the current state of the law...
