Hey need advice

So basically i have started writing children's storybooks more like picture books and stuff on same genre...my ideas are original but since I'm not well off basically have zero money to invest and stay with my parents....so although I've sent my draft to publishers but its a long 8 to 12 weeks process also I don't have illustrator so i came across this concept of ebook i feel what if i create my own storybook using illustration from ai and sell it...is it breach?? Since I can't afford any illustrator now but i have my stories as my only asset with me Please guide me around this whole ebook thing
