Bar sink in basement drains very slow. Is this drain setup correct?

No it isn't. Cut that out and put a san tee to get the trap and the AAV off the top. Run the AAV as high up as you can

Am I keeping the trap the same and just cutting out the 45 degree t and putting a sanitary t with a horizontal line and putting the vent off the horizontal line? Could you maybe draw it for me? Sorry I’m very new. I see how avv’s are installed online and they’re all installed off a horizontal but the drain goes into the wall and not straight up out of the ground like I have here

Cut the pipe right below that wye and put a coupling on and then raise it up for a tee. On top of the tee take your
AAV up as high as you can and then get a regular p-trap and put it in the tee. The trap that you have is a S-trap.
Sorry I would need my young grand son here to show me how to draw a picture for you. There's guys on here that can. LOL

With the vertical drain line so close to the sink drain, you will need to rotate the P-trap to provide a horizontal run to the sanitee. But here's a rough sketch of what TomFOhio was indicating.

Wrong kind of trap., switch to a p trap., and use a sanitary tee. Guy above posted a picture., extend the top of sanitary tee high as possible with the studor vent at the top...

Your current trap can siphon the trap dry and cause sewer smell to enter

And wye is illegal to vent in that setup.,
