Ha, well I didnt see that artist tag. My bad, didnt want to throw shade.
How I got to this assumption? I was playing around with such a tool recently and the results often had a similar look to it. I also asked a friend of mine who is more into graphic design and he said it looks like 100% made like that. Also he created the attached images using a few keywords and they do look similar. Anyway, as I said, I didnt want to discredit real artists work.
