I am no help to you, however
the walk way separating the upper / lower tier of the stadium has "disabled access seating"
and again he probably doesn't fit that profile
I don't know that the Rams can provide a wheelchair, even if Dad doesn't need it, it's nice workaround for annoying situations like this (whether he'd sit in one or not is probably a friction inviting moment)
It's possible they might provide a wheelchair or something to that effect.....thought I am not holding my breath
the car disabled placard would be a great thing to have as they have to provide parking
like I said......I am no help
That all said, the ticket folks at the rams phone number have been very helpful.
If they haven't been thus far, tell the first agent to walk it up a supervisor, and get them to assist.

that's all I got
and apologize if this entire response is ultra annoying.
