Right, but the two words used are "man and male" not "man and child". That's a more broad statement, not a more narrow one. As in it's lumping in pedophilia with homosexuality. You'll also notice the punishment isn't for the "man" to be put to death, it is for BOTH to be put to death. So even if we take the argument "by male it means male child" you have to square away that it immediately calls for you to put that child to death. You'll also take note that this says nothing about "man and girl". If this was truly a condemnation of pedophilia then why is it limited to male children?

Well, that's clear from other bible verses, because you pay 50 shekels of silver and get yourself a new child bride in that case. (Deut 22:28-29)

If a man finds a girl who is a virgin, who is not betrothed, and he seizes her and has sexual relations with her, and they are discovered, 29 then the man who had sexual relations with her shall give the girl’s father fifty shekels of silver, and she shall become his wife, because he has violated her; he is not allowed to divorce her all his days.

The bible very clearly knows what girls are yet has no real punishment for raping them.
