If there is a potential defendant with financial resources and there is an injured party, you can be sure that some lawyer will cobble together a legal theory to reach into the deep pockets. The State of Arizona has already sued YouTube for its alleged role in damaging the mental health of juveniles. It is citing that state’s Consumer Protection Statute. My state (NC) has a very broad Consumer Protection law and I can easily envision a claim that dangerous information disseminated for profit is actionable as an unfair or deceptive trade practice. NC also has an appellate court decision that says NC courts can create causes of action for every wrong, regardless of whether there is a statute on point. Every state has their own laws, so there is no uniformity, but keep in mind that pretty much all the state consumer laws were originally based on federal law and FTC regulations.
