Actually though, Pages does have a find/replace feature but it will not accept that the replacement element carries a different style to the original

I already stated that fact. If you want to find/replace styles, you need to export to Word, and open in MS Word, or LIbreOffice Writer to perform style find/replace. Save as a Word document, and reopen it in Pages.

I think you will be hard-pressed to find any word-processing application that automatically styles foreign phrases as italic.

Pages has no character style find/replace feature, nor any autosensing of foreign phrases and their conversion to an italicized character style. It is all on you to do this manually.
