If someone with programming kung fu takes a stab at this, please post a link to your results here. Likewise, if there is a world-building software package that does this already, please let us know.
I'm not convinced that you need to pay attention to the spherical nature of the globe when using this approach to world building. Most GMs are not going to be handing out globes to their players. You could get away with constructing your Voronoi polygons entirely in 2d space.

I found a link to construct a Voronoi diagram by hand: https://www.instructables.com/Hand-Drawn-Voronoi-Diagrams/.

SciPy has a module for constructing Voronoi diagrams. The main challenge looks like it will be exporting the Voronoi diagram to the program that you intend to use for making your map. It looks like you will need to plot the Voronoi polygons and then save them as an image.
