Neighbor drove into pile of dirt left in preparation for yard work the next morning, they are now asking me for money. Am I liable here?

Location: Nevada

Hired a landscaper to add some pavers and the company they hired to drop the dirt off dropped it probably late afternoon the day before.

A neighbor is claiming the sun was blocking their view and there was no construction cones causing her to run into the dirt.

They are claiming I am liable because “I ordered” the dirt which I did not technically.
