An example that I can think of is Teaching English as a Foreign Language (TEFL), which requires a relatively short online course (for a fee, of course) and entails teaching basic english to kids from non english countries online. I’ve usually known of older and elderly people doing this but I don’t think that’s a requirement or anything lol. As far as know, the only requirements are high school English and the teaching English course.
Are there any other of these sorts of online jobs that maybe require a short course, and at least potentially bring in enough to pay for the groceries?
Most things computer based, provided you have a feel for it. If you are interested in Business Intelligence, you can learn to work with Microsoft Fabric and there are plenty of companies in the data field that are hiring, offering traineeships etc. Same goes for the more technical data engineering, software development, etc.
