No, webworms generally do not kill trees but yes, they can contribute to a tree's decline and ultimate death.

But they will survive as long as the leaf-consumption is not coupled with other environmental stresses such as additional pests, extreme moisture and temperature levels, or heavy chemical controls.

Why will plants not grow under a black walnut tree?
Walnuts release a chemical into the soil called juglone. Juglone is present in all parts of the tree, but can be especially high in the roots and walnut hulls. The highest concentration in the soil is directly beneath the canopy of the tree, but it can be present in lesser concentrations anywhere the roots are present (which can be out as far as the tree is tall). The presence of juglone can also be affected by soil type, with sandy well drained soils tending to have less of it present.
Juglone can be toxic and even fatal to some plants, while others don't seen to be affected by it. Affected plants show signs of wilting, yellow leaves, stunted growth, and eventually death.
