I know this old but I just joined and ran into this issue with my new Demello bumper.
There are kits out there to "fix" the issue.
Power Steering Cooler kit – 4X4LABS
I really like my Demello bumper but after I saw the very obvious hard lines just sticking out there asking to get whacked or snagged by a branch I wonder why they don't bring this up during the initial sales conversation or pre-install conversation and offer to install the kit as an added option. Seems like a great opportunity for a little upselling and frankly, in my opinion, is a bit sloppy for a shop that installs these bumpers every day and must have to look at those lines just staring right back at them. I don't know trucks that well but I noticed it immediately. It is a minor detail but noticeable and *so* easily fixed when the front is opened up.
You might have also noticed your windshield wiper fluid tank just hanging out there too with loose wires and hoses. Also kits to move that but there is a trade-off - it takes up the spot where a second battery would go.
