Most are not. "Problem wolves" do show up sometimes. In Netherlands we had "Bram" GW3237m. First, he just followed people seemingly unafraid. Then he attacked a jogger (who ran away) and a 6-year old boy (grabbed him by the chest and tried to pull him in the bushes, bystanders hit the wolf with sticks so he ran away). Judge in Utrecht gave an order to shoot the wolf dead, which was done and now it's back to just sheep being bitten.

I've heard from my farmer friends that not all sheep declared to have been bitten by wolves have in fact been bitten by wolves. There is some insurance fraud with that. Not sure how widespread

Extremely widespread.

Suddenly statistics will show that no sheep or cows die anymore by illness, accidents, old age or pregnancy gone bad, after government starts paying for wolf attacks in some area.

Every single time, farmers will soon realize that paying for medicines for an old cow is a worse deal than borrowing a mastiff from a friend and being paid. People tried to be paid for the bony rests of a barbecue. (Yep. really). People tried to be paid twice or thrice for the same cow, just moving the corpse around. For some reason wolves always start eating the most yummy parts of the cows first: the plastic identification tags in the ears.

In Spain some farmers never ever sold a cow or paid taxes. Their entire activity for decades is: buying foals in a province by 50 euros, moving to another and leaving then alone in isolated places known to have wolves, to cash 150 euros of our taxes by each foal. Rinse and repeat. Ka-ching.
