I must admit I thought it a bit odd that they do not offer to fit all SMT parts that LCSC can supply, I get THT would be done by hand etc so not worth their while, some parts are extended but it'd be nice to have that option, yet you can order the bits they don't fit and get them delivered with your board just not assembled on the board, I'm sure there is a reason for it, like they only offer assembly of one side, i'm sure in time it'll come that they offer all parts and both sides.
