No. Leather Jacket can only prevent damage from the opposing minion's strike.
Incidentally, the backlash damage from Blood of Acid is not from a strike at
all, but is environmental.

No.
The BoA damage is considered 'enviromental', i.e. it's not considered to
come from a strike, and therefore it is not damage from a strike, as
required by Leather Jacket. This means you can't use Skin of Steel or other
similar cards either.
You should check the Rulings and Clarifications online, I think it's clear
enough there:
