Of course not. The regulations should be written to state the
conditions that allow safe compost tea to be made. Aerobic through the
whole brew cycle. Lots of good aerobic bacteria, fungi and protozoa
growing to compete with, inhibit and consume the E. coli.
That gets rid of the E. coli and human pathogens.

My understanding is that E. coli 0157h7 is also more acid resistant than most other strains. That makes it much more dangerous to humans than other strains and also limits which rumanent manure will have it as the dominant type, properly fed cattle run a alkaline pH due to their ability to secrete sodium bicarbonate in their saliva, but this is overwhelmed by high grain feeding. Manure from high forage ration animals should be much safer than feed lot manure.

If there is no E. coli in the starting materials, then why say there's a
danger of E. coli. At least compost tea made with non-manure materials
should have been allowed.

But no, no tea at all can be used.

Anyone else feel like there's a hidden agenda here?

I wouldn't discount arrogance and stupidity, much more common than outright conspiracy.
