I doubt that the allelopathy of the Black Walnut trees had anything to do with those pines dying.
Check the bark on the dead trees for pin holes and you might even pull some of the bark off to check, you are looking for evidence of pine borer.
While I don't have any pines on Buzzard's Roost, we do have red cedars (sacred to us) and they too are subject to dying from borer activities.
The few we have had die, that is what killed them, found out by stripping bark and uncovering the tunnels made by the borer larvae.
