240V GFCI Receptacle?

I have an existing window air conditioner that was installed in a wall. It has its own dedicated single 20A, 240V receptacle. For some reason, the receptacle was installed outdoors, under the A/C, with the cord plugged into it. (I have no idea why they didn't just break through the wall and put the receptacle and cord indoors.)

My questions:

1. Being 240V, does this receptacle need GFCI protection, and if so, does such a receptacle exist for that purpose?

2. Do I need a 15A 120V convenience receptacle nearby?

1) No, and no, no such receptacle exists. If it were required/desired you would have to use a GFI breaker, but it is not required.
You should however use an "in-use" cover on the box.

2) No.

The other question to ask is whether the cord has rating suitable for exposure to sunlight and wet locations.
The weather can destroy the cord pretty quickly and create a hazardous situation.
