Is it necessary to remarry a girl who has not shortened her hair after her 'Umrah when she was young and before puberty, according to the madhhab of Imam Abu Hanifa and the view of those who hold that a child is not accountable, and is this considered a divorce?

This girl is not considered to be in a state of ihram; therefore, there is no objection to contracting marriage with her, and it is a valid marriage that does not need to be renewed. The madhhab of Imam Abu Hanifa holds that the marriage of a person in ihram is valid in all circumstances.
