Correct. There is no U.S. law which compels the installation of a back door under a gag order. Gag orders are a thing, but they apply to _providing_ information to law enforcement, not collecting it in the first place.
There is something called lawful intercept which requires telecom infrastructure companies to install wiretapping points in their networks. These are openly installed, not under gag order. But it is possible for law enforcement to activate them with a warrant that's under a gag order. And again, these are in telecom infrastructure, not user applications.
The FBI did attempt to compel Apple to implement back doors in iPhones about a decade ago. The attempt ultimately FAILED in court.
