At the very least, GitHub Copilot will have an easier time with an SDK loaded into context than an API documented only on the web. If the customers are using typescript then they'll have some red squiggles that at least some of these people will bother to read prior to asking for help. The uninformed consumer of OPs API will probably be more comfortable to work with an SDK instead of writing their own clients.

The way I see it is that OP can either complain about customers being annoying, which will happen whether or not OP does anything about his problem, or OP could proactively produce something to make their product better for the demographic they're targeting. At this point it's pretty clear that the users would rather be helped than help themselves, so meeting them where they're at is going to be more productive than trying to educate them on why they suck at both coding and asking for help (or free work).
