My client asked me to replicate their AI pictures after I sent first round of designs

After I sent my first round of designs to a client for feedback, the client scrapped everything and told me to 100% replicate AI pictures in Illustrator to be print ready. The AI pictures do not follow the creative brief that I was given and do not follow established layout design principles. While replicating AI work goes against my ethics, I do not know how to go about this. I am a relatively new freelancer and there was no AI clause in our contract upon signing (now I know for the future) nor was there an established extra fee for this situation. I am also frustrated that I wasn't even allowed the chance to make revisions as is typical and expected with working with clients. While I know that the client probably just isn't aware of how this works, I cannot in good faith just agree to do this or work with AI.
