The causality is the other way round: air spirals upwards and BECAUSE of that there is low pressure on the ground. The question should be WHY does the air rises upwards and WHY does it spiral?
The spiralling comes from the coriolis effect. The rising comes from differences in mass density (lower density rises above higher density). That density difference may come from temperature differences.
High pressure areas have the contrary effect: air falls down and causes high pressure on the ground.

Low pressure air spirals upwards due to the Coriolis effect, which is caused by the Earth's rotation. As air moves from high to low pressure areas, it veers to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, creating a spiraling motion. This is known as the geostrophic wind pattern.
Persistent low-pressure zones can lead to uplift of warm, moist air, causing it to cool and condense, resulting in heavier precipitation. Additionally, the convergence of air towards low-pressure centers can enhance cloud formation and rainfall.
The convection cells radiate heat.
Winds occur as air moves from high pressure to low pressure.Wind occurs as air moves from a place of low air pressure to a place of high air pressure is a true statement.
Yes, a tornado is indeed a violent windstorm characterized by a rotating column of air with intense low pressure. It forms a narrow, rapidly spinning vortex that moves over land, causing significant destruction in its path.
less dense and rises, creating areas of low pressure. This leads to the formation of convection currents as the warm air expands and moves upwards.
