How many LMs I need for such a large project?

We do not recommend more than 2000 objects per LM. Your setup should work if master LM does not require to get all values from all objects. You will need to correctly configure KNX/IP filtering table to prevent overloading both LM and KNX/TP lines. From reliability point of view it's better to run all local stuff like scenes on each line separately and use one master LM for visualization.

So, if I understand, each LM must have only its vis. structure and the related objects it uses to run its own scenes and/or scripts, right?

The master LM doesn't need objects at all, but just visualize others in frames, right?
