Mosquitto is an MQTT broker and it runs on computers as any software does. But you're right, Mosquitto doesn't run on an Arduino because it hasn't the resources to run it. The same is true Espressif boards and most other boards that are programmed by the Arduino IDE.
But Mosquitto runs perfectly on the Raspberry Pi and many other small Linux based ARM boards. Just install it on your Raspberry Pi and point your nodeMCU to the Raspberry Pi's IP instead of Adafruits'.

is there a way, where i would use offline broker.

Yes, but probably not as you expect it. You can Mosquitto on the Raspberry Pi and access it locally by other programs. The Raspberry Pi is offline but it still has it's internal network layer available, so the MQTT service is also available.
