The plaintiff doesn’t say that Disney owns it, though. They are basing their argument on the fact that Disney posted the restaurant’s menu on their website. The website is also under the Disney+ TOS. So, if the plaintiff is correct and Disney is liable then the TOS probably applies.
The TOS doesn’t say anything about crimes like murder, and of course you can’t waive that anyway.
What it does say is that any disputes arising out of the use of their website are subject to arbitration. If the plaintiff is correct and Disney is liable because they posted the menu on their website, then that would be a dispute arising out of the use of their website.
