You can't have ticket for a passenger whose name changes at the midpoint.
You could likely do it as an EXTRASEAT on LAX-DEN and then a regular ticket on DEN-XXX, but I suspect this is OP's attempt to get a better fare (LAX-XXX is probably cheaper than DEN-XXX).
Perhaps ANA would be willing to drop the last segment.
Yes, they can do this - with miles or money, but it needs to be done via UA reservations and probably escalated to a more senior agent if the OP does not have status. The separate ticket will be EXTRASEAT/Lastname and be a completely separate PNR which will be cross-referenced with the PNR on their original ticket with the extraseat assigned to be adjacent to the original PNR seat and notes in bookings to prevent a seat change. They will need to check-in twice, print two boarding passes (I strongly suggest using kiosk for the extraseat PNR and print a paper boarding pass), and at boarding time, make it clear to the GA, preferably a supervisor that the paper boarding pass is for their extra seat booking - and as always, be prepared to defend the extra seat from poachers, or from a confused GA who makes a seating change or mishandles the pre-departure seat count.
