In nRF5 SDK for Mesh, the examples uses the simle_hal.c for this functionality. You can use the hal_led_pin_set() function to set the LED on or off.

/**
 * Sets the LED for the given PIN.
 * @param[in] pin   LED pin number.
 * @param[in] value @c true for on, @c false for off.
 */
void hal_led_pin_set(uint32_t pin, bool value);
