I'm aware that the requirements are lower
Hmm, not much. You have to pass the same theoretical knowledge exams and the standard required on the skill test is exactly the same.
Also, do the extra 10 hours I need to go to PPL have to include an equal amount of instructor led training,
Yes, in fact you have to complete a course of training at a DTO or ATO:
FCL.210.A

Applicants for a PPL(A) holding an LAPL(A) shall have completed at least 15 hours of flight time on aeroplanes after the issue of the LAPL(A), of which at least 10 shall be flight instruction completed in a training course at a DTO or at an ATO. That training course shall include at least four hours of supervised solo flight time, including at least two hours of solo cross-country flight time with at least one cross-country flight of at least 270 km (150 NM), during which full stop landings at two aerodromes different from the aerodrome of departure shall be made.
