To stay warm. Are you so worried about people assuming you aren't wearing a tie that you need to cut a v-shaped hole out of your sweater to drive the point home?
You can always do the Agnelli tie outside the sweater instead
I don't know that there are any set in stones rules but I reccomend that you only wear v necks with suits even if theres no tie. Plain colors and modest patterns are also best especially when worn in a bisnuess setting. Also make sure since sweaters fit fuller in the midsection that you have enough room in the body of the coat so you don't distort the fit or the jacket when wearing one.
Anyone who takes off their tie anytime they get cold & require a sweater is a masochist. If you want to talk about how lapels or collars or underpants are just societal conventions then there are other fora where you will find easy validation.
No dice. Unless the crew-neck completely conceals the tie, which is generally not the case, you're going to look like a dork. Get some v-necks if you need to wear sweaters at the office.

+1. The V-neck is best and one that's a bit on the snug side or with a suit thats notslim fitting or you're going to look like you have a spare tire swimming around your waist. Might even go down a size for the sweater or go with a vest if you plan on keeping the jacket on all day.
^^^^ new here...........if your not sure about the sweater, thermals are awesome and warmer than the sweater vest.
Here though is someone who can pull it off
