"The Late War Between the United States and Great Britain" was published in 1816. You can read it for yourself and see how much the Book of Mormon was copied from it. It was an extremely popular book in its day, evidence by how many copies still exist. A real translation of old writing done by an American in the 1800s would have been in current English, not in pseudo-Elizabethan English similar to the Bible. It was done to fool gullible people.

The Bible has been confirmed by countless archaeological sites and contemporary records by other civilizations.

The Book of Mormon has not been confirmed by anything whatsoever. The gullible leadership has been taken in over and over by charlatans with counterfeit texts and artifacts.

BTW, the site is Khirbet Beit Lei. References say that Lei, or as you say, Lehi, means jawbone, supposedly indicating the possible burial site of Samson. There are still zero archaeological sites in America associated with the imaginary people in the Book of Mormon.

So there is zero evidence for its truth, and a lot against it. And yes, I have read the whole thing. Years ago, a couple of the young guys in suits on bicycles came to my home, and I knew the book better than they did. They gave up and left.
