Akvan said: “The relevant pali section in AN10.92 is “Pāṇātipātā paṭiviratassa evaṃ taṃ bhayaṃ veraṃ vūpasantaṃ hoti.” Does this mean that a Sotapanna sees the perils of these five aspects (killing life etc.) and therefore tries to stay away from these, rather than completely eliminating them?”
That is right. “pativirato” means will not do those things with liking.
But a Sotapanna is absolutely prevented from doing are those five serious crimes: killing one’s father, mother, an Arahant…
