One of the features of English has been its capacity to borrow and assimilate words from a wide variety of languages. When first imported, we tended to format them in italics to show they were borrowed.
In an online age, italics are harder to read on screens and present problems for readers with visual impairment.
As a result, generally do not italicise words from non-English languages unless they are freshly imported into English and will be unfamiliar to readers. And prefer an English alternative if there is one.
