reduction using 2 inches of rigid insulation between the blockwall and backfill on an 9 foot high basement wall. Any information on this thought will be appreciated.

Sorry, no reduction. Use same lateral pressure. Most rigid insulations can carry a lot of weight over a square foot. Even if insulation compresses the lateral force would be the same.
