Unfortunately I do not, and I’m not sure he ever mentioned his drawing program back when he regularly made art

That said, if you want to produce your own art that has a similar visual style, let me offer you my personal advice as one budding artist to another: your choice of drawing program is largely irrelevant to the quality of art you can produce. As long as you aren’t using MS Paint, you can learn to be proficient in any software. If you like a certain art style, you can achieve it yourself with many different programs. Choose one that’s free and accessible to you and just learn it (via online tutorials, etc.)

Good luck!
