I’d like to have even just 500 of them made. I have so many cute little toy ideas that would make good use of LLMs (very simple toys), more of these ideas than actual app ideas now days.

If you want to do it alone you'll need simultaneous knowledge in electronics, mechatronics, mechanical engineering, design-for-manufacturing, parts purchasing, and procurement. That's before you build your product in a factory, or if you choose to do it yourself.
Simone Giertz is an incredibly smart and talented person with a lot of this knowledge, and even she will tell you how hard this can be.
