Solid lumber would be my choice if they are exposed to the element but I much prefer Gluelam for a much better look then LVL. All engineering lumber is more stable compare to lumber. If they go under a roof, gluelam is the way to go. Stains nicely especially dark color and being way up there. I suggest coat it with flat (for the natural look )or semi gloss poly. Paint the exterior tails to keep from the element if its under a eave. They do cost more compared to lumber.
Look at rafter table to get the correct timber size or call your local lumber yard, not HOme Depot since those guys have no clue, and they will have the correct size for you. My kids and I built our second story deck using treated 4x8, 18' span, 12" center. I wanted to eliminate bounce. Painted the underside for protection.
