query: new respa requirements if a portion of the fees will be paid by the seller do tolerance levels still apply

Yes.  Costs that are typically buyer costs must be disclosed on the GFE even if the seller has agreed to pay a portion of the buyer costs.  The credit from the seller will be placed on page one of the HUD and will not be included as part of the tolerance calculations.  That means costs that DO fall within the tolerance rules must be accurate even if the seller is paying a portion.
