"Theoretical" is overselling it, you need novel nonstandard physics to get black holes out of the LHC. Indeed standard physics cannot predict LHC black holes because the Standard Model and general relativity are famously incompatible at these scales. Moreover, if Hawking radiation exists, as is now widely believed, the lifetime of a hypothetical atom-mass black hole would be much, much less than a Planck time.
