"Lb Foot is not a measure of pressure" ... correct. It is a measure of torque.
A pound-foot (lbf⋅*ft*) is a unit of torque (a pseudovector). One pound-foot is the torque created by one pound of force acting at a perpendicular distance of one foot from a pivot point. Conversely one pound-foot is the moment about an axis that applies one pound-force at a radius of one foot.
