No sweat lol - & it's good to question, I suspect there could be some shenanigans afoot when it comes to some ebike retailers, completed bikes in particular. There is a significant price difference with LiFePO4 sometimes being nearly twice as much as other "lithium" batteries due to their chemical composition, longevity & safety... and if folks think "lithium is lithium" there's some obvious wiggle room in the profit margin depending only on what sticker has been put on it...
...but I'll admit that could just be my tin foil hat whispering to me again lol, it could be as benign as a "one case fits all" scenario and they just don't bother to label differently, I s'pose it all depends on what's actually inside & how much was paid. If they really care, cracking open the case usually isn't difficult. Making small, careful cuts in the outer protective wrap, in the small valleys between the cells so there's no chance of damage/nicking the cells or wiring will allow the cell's casings to be examined and they're labeled/stamped with their composition & date of manufacture, sometimes with their additional specific specifications (volts/ah)... but it may not be in english ofc
