Look, parents are cautious about who they let interact with their kids. The truth is, you wouldn't leave your kid to hang out with a rando. And an LLM isn't even a rando. It doesn't have the reasoning, the common sense or the decency of any random human being. You should not let your kid just talk to an LLM, no matter how well designed it is, no matter what safeguards are in place. That LLM is not a person you trust, it has no accountability.
That toy probably shouldn't be on the market, but the parent definitely should not have bought it, that was the most significant example of poor judgment here.
