Are there bank accounts that have a person watching every transaction and can call you to ask why you went to a Bitcoin ATM? A bank account an elderly person with dementia could use?
How do I know? If you happen to have been a school teacher for 50 of those years, you keep excellent hand written notes of the events, that make your relatives sick to their stomachs.
While not quite what you asked, a service like this would at least provide an additional barrier, before someone hands over their net worth to a scammer.
The next step after that, often used for elderly people, involves a full power of attorney: someone else is completely responsible for their finances, and hands them either cash or a debit card with a small amount of money that they can use however they want. But that is for extreme cases.
For anything less, its too much work.
