That sounds like a solution looking for a problem though, i see plenty of arguments against throwing critical safety information that are in charge of peoples lives into an LLM "just in case the result is better than the result that the current battle-hardened systems already provide"
To properly test an LLM based emergency system against the current as-is system there needs to be a way of verifying whether the LLM detected emergency is classed as an emergency as-is. If this information was available publicaly it could enable bad actors things like stress-testing the EMP-tolerance of the current systems or what level of malware infiltration is detected.
