Not all laundry faucets are wall mount and I think usually have no low flow regulators. Here’s a very good brand (Kingston Brass) that’s inexpensive and good flow rate, 4 gph.

A simple search on high flow rate faucets gets multiple hits on various styles.
I found a good number of roughly 4 GPM 4” centers faucets, but... This usage is a kitchen sink faucet with 8” centers.
At this point my only option is replace the brand new faucet with something like what I linked above (and try to figure out something for the side spray) or put a single hole single temperature “drinking water faucet off to the side.
Well, I guess I could really hillbilly it and rig up something from under the sink with a water hose...
