I have some experience in the past regarding this, The best result I found thus far is to let AI generate High-res image and then use that in image-to-image with some Pixel art loras to generate a Pixel art. This results is sometimes of desired style but is not accurate pixel-wise. However, it is less tedius to just clean up an image rather than to make something from scratch. There are also addons for Automattic1111 which have fixed pallet and resolution binders which may help.
