Kalen:
From the "Strokesaver Guide to the Classic Courses of GB&I" --
The Dell at Lahinch is listed at 142 metres from the tips, 137 from the yellows. It has a large mound fronting, in back, and to the right side. There is a little pot bunker to the left-front of the green, but not encroaching on the green. There is a tilt to the area left of the green that presumably feeds balls toward the green.
The green itself is quite narrow -- 18 yards wide at its widest, and is much wider than it is deep (a guess, but 30 yards wide?) The right portion of the the green is a bit "fatter" than the left portion, which is quite narrow, perhaps only 12 yards wide. The strokesaver picture looks like one might be able to see a portion of the fatter, right-side portion of the green from the tee. The green is titled ever-so-slightly, with the right front slighly closer to the tee box than the left back portion of the green. But it's not much of an angle at all.
From what I've seen of it, in this depiction and other pictures, it seems to be aligned quite closely to what I've seen of the Dell at Erin Hills -- pretty much a blind tee shot to a wide but very narrow green, with the terrain around the green playing a role in funneling or kicking the ball toward/near the green.
Hope this helps.
