In Writer, press Ctrl+H, in Other options - Format - Font - Style select Italic and it wiil be search italic and normal, not only italic.
I think this is the same as described here: https://bugs.documentfoundation.org/show_bug.cgi?id=103400#c3
Do you agree?

Find: Italic/Regular incorrectly
Yes, it looks like the same bug. I try to find Italic in new small document and it finds correctly - only the Italic.
But in some my capacious documents, it finds Italic and Regular (Normal) as I wrote, but now I discovered not all Regular.
I modified one capacious document to the small one.
In incorrect-find-italic.odt try to find d (Italic, Regular, No Format), description is also in document.
Thanks, I added the information you provided to the other report, let's close this.
