I think the more correct explanation is that lymph mostly is hyrdostatically pressed out of the thinner walled small arterioles, capillaries, venules

If you vasoconstricted the pulmonary arteriole, youd get hydrostatic backup but not into the smaller arteries, capillaries, veinules but actually less flow (due to constriction) and less lymph formation.
