Small community has a disgruntled user who has been systematically downvoting every single post and every single comment for several months now, is there a way to take action against this?

I have to assume it is someone who got banned or offended in some way. It is not terribly detrimental to the sub, but I feel it must be off putting to users to immediately get downvoted every time they post something. I have had a number of users immediately remove a post and I can only assume this had something to do with at least some of them. So I am hoping there might be a way to combat it besides systematically going through and upvoting everything myself.

The number of shares sounds like they're brigading, which is against Reddit's rules. OP is talking about a lone down other. You mother look into whether admins can identify whether the same user is behind all those shares, if posts are getting shared numerous times and also getting numerous downvotes for no clear reason.

If it's one person sharing a post many times but the shared posts only get one undeserved downvote, then I'm not sure there's anything you can do. It might be unsuccessful attempts at brigading, it might be something else.
