What is Louis Vuitton font called?

I'm curious, could you please tell me the name of the font that Louis Vuitton uses in their branding and designs? I've always admired the elegance and sophistication of their branding and I'm interested in learning more about the specific font they use to create such a memorable image. Is it a custom font designed specifically for the brand, or is it a widely available font that can be used by anyone? I'd love to know the answer to this question, and I appreciate your help in shedding some light on this topic.
