Adobe’s October 2023 update adds a new Lightroom Lens Blur panel. It’s flagged as Early Access, so it’s still in development, but you can use it right now and it’s actually rather impressive!
Lens Blur (Adobe Lightroom)
A new feature in Adobe Lightroom that uses AI to identify key subjects and three-dimensional depth in photos. It can be used to isolate the subject and blur the background both much more quickly than conventional techniques and rather more convincingly too.
