Anything organic that's not rotted down will take nitrogen from the soil
but
in the case of bark chips this isn't going to be a massive amount. It
wouldn't be worth thinking about especially with the compost under it and
may even assist with your control of the grass. In time the nitrogen loss
sorts itself out anyway

indeed, and if you are not going to grow anything there, the whole point of
mulch, why bother fertilising? Fertilise what? If you do put some plants in
you can fertilise their roots with a slow release fertiliser.
