Have you tried a different terminal app, such as Ghostty? https://ghostty.org/ has a Mac build, and handles italics properly. That might solve your issue without having to edit any configuration files. Plus, as a side benefit, Ghostty ignores the ANSI color codes for blinking text, so you won't ever see blinking text again.

I am wondering why people are so hyped about Ghostty? I gave it recently a try coming from kitty. And I had to configure stuff that worked out of the box with kitty, like Ctrl-Enter support and other key combos for agent harnesses. I like the development model of ghostt. And the developer really cares about creating great building blocks, e.g libghostty. But I am a bit underwhelmed.

		I feel like the ghostty hype make more sense as excitement around the direction of terminal infra than a claim it is the one true terminal. Kitty's fine and if you are happy with it there's probably no good reason to switch. Tangentially I also kind of feel like there is some level of deification of Mitchell's products but that's a diff topic.

		Might depend on what you're comparing to. Came from iTerm2, and Ghostty is much faster and minimal.
