For LFLB you are right only if operating below this weather or at night you need training. Today it is very simple, you can only operate on part SPO, NCC or CAT. In any of these situation you have an accountable manager ( that can hold as many functions as it is humanly possible), Part NCC you have a chapter for training, in Part Cat a part D, etc..
Therefore a statement from the adequate portion of your manuals with the appropriate references and of you go.
The operator is responsible for this. LFLB and LFLP next door requires training in a FSTD ( not an FFS) should you want to operate in there below minima, or go there in VMC and practice..The simulator and its visual do not need to be approved by the authorities, again it is the operator responsibility .
By the way it is the same for all airport that fall into cat C (LOWI, LSGS, etc..)
