If UA was late you'd go to UA to deal with re-bookings. If UA was on time and you just couldn't make the connection ... that's not easy, start with LH if you still find someone at the gate. They would likely pay for accommodation, unless the UA flight was late due to weather (again, only in Y or when not SAG).
UA might rebook you into full Y which will earn some nice bonus, but there is no guarantee. LH held a flight for me in June ... but I was in F. Doubt they will do that for a Y pax.
