Morphology
The constituent 'mouth' clearly signals speech and 'off' can function as an intensifier, so there is a partial, metaphorical link to talking; however 'shoot' in its literal sense (to fire) does not directly yield the sense of speaking carelessly or boastfully. The phrase relies on a figurative extension and idiomatic pattern (similar to 'mouth off'), so a B1 learner who only knows the literal meanings would likely not fully predict the exact pragmatic sense without prior exposure.
Etymology
The idiom shoot one's mouth off may come from the image of someone shoot words from their mouth like bullets, saying things quickly and without thinking. That's why it now means 'to speak carelessly or boastfully'.
