In a cross-sectional studies, if I am collecting different outcomes in terms of complications of a therapy (e.g. FDP, RDP or CD) and take their follow-up complaints and findings, can I utilize Kaplan Meir plots to also predict the survival rate?
No . KM curves compare rates of change; by looking at the units you can see which group is moving the fastest. See:

for details. Best, David Booth
Technically you can do Kaplan Meir plots based on the data you have but that will be misleading, as your cohort is not proper. Moreover you can't predict the survival rate based on Kaplan Meir method, rather it can be estimated.
