Its not ‘FAA law’, it’s DOT regulations. And those DOT regulations don’t apply to travel agencies. And it doesn’t have to be ‘refundable’ per say. AA, for example, used to not allow a refund, but instead allow a free 24 hour hold before purchase - which is allowed under the regs.
As mentioned by WineCountry, OTAs are not required to refund within 24 hours. Many do (Orbitz, Expedia, etc.) but that is used as an incentive for people to book with them, but isn’t required.
