I just had a look on the details:
LH435 arrived on 16-Nov in MUC at 15:42 (instead of planned: 12:50).
LH1654 MUC - OTP planned departure at 14:55 left MUC at 16:24.
That's 42 minutes after your arrival. That should have been enough time for the transfer.
Why were you not capable to get the flight? Did LH told you that you cannot reach it? Did you rebook to the MUC - OTP leg already before departure in ORD yourself?

LH may have an argument stating that it was feasible to get the connecting flight (which was also delayed [by 1h29min at departure in MUC]). Therefore they may reject your claim.
