Can a 14-year-old girl date a 19-year-old boy without a parent's permission?

Until the age of 18 minors are bound by their parents. This is due to the fact that the parents are legally bound for the actions of the minor. I would not do it without the blessings of the parents. The 18 yr old could be put in jail. In the "eyes" of the law, no. As stated by the previous poster, if the parents of the minor object to the relationship it could result in some serious legal trouble. A 14-years-old is not considered of age, for any type of relationship with an adult in any state. All states reserve the right to enforce and prosecute the adult offender when it pertains to laws governing minor and adult relationships. The relationship itself does not necessarily have to be of a sexual nature for authorities to take action; and said authorities do not need the co-operation of the minor or the minor's parents to do so.
