My need is to create VSAM ( KSDS ) file with 4GB data. Is there any JCL to load random data in VSAM file.

Look up the IBM utility IEBDG. That can generate records that can then be copied into your dataset using REPRO or SORT for example. You'd need to generate the records that match the defined key and maximum RECORDSIZE for the KSDS.

You also would have to define the new VSAM dataset with Extended Format and Extended Addressability to be able to exceed 4GB in size. Ask your Storage team what DATACLAS is available that provides Extended Addressability.
