You are correct, there is active research on this. And words and pictures are associated in models like stable diffusion. There has been some success combining GANs and LLMs, but it is far from a solved problem. And as the training data gets more complex the required training resources increase too. Currently it's more like a confusing barrier than a happy extension of LLMs.
