Does Alignment need to be checked due to car accident

[Hershey]

Called the service center and spoke to the manager . Said all within specs and can't guarantee any improvements . So , wlll pass on it . May take it to a tire shop that checks alignment for free and get their opinion . Had to fill up the car with 1 blinking bar . The Eco read .146 (40.6 ) lower than the calculated gas mileage of 40.74 . Had been anywhere from .4 > .6 lower before the alignment . This could be do to 2 cold mornings of upper 30s' > low 40s' and her having to wait for school buses . So , not sure if any impact from the alignment . If so , not so bad . Tires are set at 36 p.s.i..
