The requirements for PPL (A) conversion from FAA (ICAO) to EASA are quite high. Firstly you must have 100 hours logged, you'll also need to do a EASA class 2 medical, repeat the Air Law and Human Factors exams and undergo some training for the SEP rating and redo your check ride.
Generally speaking when you are under instruction the hours can't be classified as PIC which makes sense. How could you be the PIC of an aircraft for which you don't yet have a rating. That said as far as I know the 100 hours are not PIC hours, just logged hours.
