Avoiding S bend under Ikea sink

[SEYMOUR]

Hi - We're installing an Ikea Godmorgan 40" wide vanity (YES, another Ikea plumbing issue!). It's on an exterior wall (Quebec, by the way) and the plumber put Pex supply lines and a 2" DWV pipe through the floor and close to the wall.
The Ikea trap will have to connect to the drain via pipe(s) turning 180 in order to go south. Does this make it an S bend? Should we have an AAV as part of this assembly (and if so, where) since the drain pipe travels about 6' before connecting with the original 2" vent? Can you suggest a list of parts & sizes still needed please? I'm asking because I'm not happy with the bills we've had so far.

Thanks - and stay safe everyone !
