The hypothetical you state only matters once you have a game! The biggest risk by far is not AI assets -- it's finishing the game.

So if AI increases your odds of finishing, go for it. Then once you have a game, more people will care about whether it's good than whether you used AI assets. I suspect there will be lots of interest in how you incorporated AI, maybe even moreso than otherwise. You could alternatively use the AI assets as placeholders and intend later to replace them with hand-drawn, if desired.

When I made games, I had zero interest in making assets but wanted to understand every detail about graphics engines. I just grabbed random mediocre assets from online. I would have definitely used AI to make assets but done the coding myself.
