Your infusion center link must be more up to date than this HHS one (https://protect-public.hhs.gov/pages/therapeutics-distribution#distribution-locations).
An infusion center shows up locally for me on the locator at your link but not at the HHS link.
In Ohio I’m watching IVX Health. An established business providing a range of infusion therapies.

Don’t know if they will be handling the Regeneron. I couldf also wish there was one within two hours’ drive, but that’s a price I pay for being as far out of cities as possible.
