Yes, IPs are PII given they can be linked across websites. In addition, many ISPs in the US do dynamic IP assignment but will let you keep your ipv4 for years if you don't go offline for too long (i've gone 24 hours without the router connected to the internet on ATT without losing my IP). And the 'business' requirement is more about "doing business" in the state and not "the service provider is a legally registered business", so individuals also must comply.
