“Life Story” is used jokingly after someone sends an unexpectedly long or detailed text, as in “damn, thanks for the LS” after a lengthy explanation.
Laughing Silently

LS in Biology and Science

On most modern game controllers, LS refers to the “Left Stick,” the analog stick typically used for character movement, distinct from the right stick, which usually controls the camera.
LS in Work and Business
In business writing and contracts, the LS meaning often overlaps with its quantity surveying use, “Lump Sum,” referring to a single, fixed payment rather than itemized or hourly billing.
