OpenAI doesn't have an existing business based on licensing Studio Ghibli content, so the only option Studio Ghibli has to stop them is to sue them and hope that OpenAI is found to have infringed their copyright.

Bilibili does have an existing business based on licensing Studio Ghibli content, so Studio Ghibli can threaten to refuse to sell them distribution rights for future releases, even without a lawsuit.
