Google is testing using the italic font type for the links in AI Mode. So the links have a bit of a slant to them, compared to the other text in the AI Mode response.
This was spotted by Gagan Ghotra who posted this screenshot on X:
You can see the two links, The Hollywood Reporter and Byrdie are both blue, underlined and italics.
I think anything that makes the links more clickable is a good thing.
Forum discussion at X.
