I have an old Dell Laser Printer that works amazing and am trying to set it up for wifi printing. The only driver available for this printer is a .sit file. Any advice on how I can utilize this on my new macbook air with macOS Monterey?

Unless that Stuffit container's (.sit) driver is a 64-bit driver specifically compiled for use with macOS Monterey, it is unsupported as Monterey requires (compatible) 64-bit drivers and application code.
As you say it is an old Dell laser printer, contact Dell about the unlikely macOS Monterey driver support.
The very fact that this is in a .sit file indicates that it is very old. Even if you can decompress it, it practically certain that the drive won’t work in Monterey or any if the recent versions.
You will have a slim but still better chance if you can use it with a generic PCL or Postscript driver - if the printer can work with one of those.
