That’s not something the plugin supports, but it’s probably possible with some custom code.
I mean, it should be a filter somewhere, maybe at google map itself?
you speak your self about t this here:
https://wordpress.org/support/topic/displaying-the-map-in-difeerent-language
and you say, the language filter is added!
How do I submit the language filter?
Thanks

also here:

you describe in version v1.10 (3/30/2013)
Added a filter to allow changing the language the map is displayed in.
Where can I change that filter to change the language of the maps?
Oh, that’s right, I’d forgotten about that. One of the comments on that thread has an example of the code you’d need to add to a functionality plugin.
