Not specifically LLM, but it looks like generating fonts with GAN is the subject ot this work: https://arxiv.org/abs/2203.10348 https://arxiv.org/abs/2203.10348 "Our goal is to generate fonts with specific impressions, by training a generative adversarial network with a font dataset with impression labels". The PDF contains interesting examples of Latin-based fonts generated by suggesting different impressions.
