It should be on the personal profile section in your M&M account (based on my experiences with other airlines). I was on LH F MUC-SFO (on an AC ticket) and when I did my OLCI, it appeared, likely because my GE info is stored in my profile and such. Or, I may have entered it at OLCI. But it was great even if ex-MUC had no TSA Pre line or screening at the time.
Also, check LH's API page "Visa and immigration data" and see if there is the option there.
