The article said it was possible to register an LLC in those states without a name, and the CC is (apparently) tied to the LLC, not the owner or employee.
It's not like they'll find a homicide tied to a CC and then be like, "oh, the CC is in the name of an ownerless corporation, I guess we're out of luck".
The owners are recorded when the LLCs are filed with the secretary of state, however these states are simply willing to keep the identities of the owners private, without publishing them as most other states do. As in most other states, you do need a Registered Agent, but you can delegate this to an attorney or company who serves to receive legal notices, correspondence, etc.
If there is any type of law enforcement investigation of the company, police would simply go to the secretary of state to determine the owners.
How hackable/social engineering proof are these state agencies? How likely is it that they are already compromised by people acting as resources for federal and non-governmental organizations?
In 2019, one should be most worried about throngs of people who have less income and delusions of grandeur who can organize their groupthink online.
