Question: The trunk of my cherry laurel has rows of holes all over it. Is that something that will kill it?

Answer: No. Those are holes drilled by sapsuckers or woodpeckers. They do no damage to the plant, nor do they indicate the presence of insects that might harm the plant. Use a sticky repellent such as Tree Tanglefoot to discourage them, and seal the holes with black pruning paint to stop their sap flow.
