Legal Question in Civil Litigation in Illinois

Void? No, you don't want it "void". You mean cancelled or terminated. Void could mean it never existed! You want it to have existed because that's the document that tells what the landscaper's obligations were. Now if as you say fixing the edging was in the contract, that's one thing. If it was not you need to show that fixing it was added by agreement, and that should be in writing. Then his failure to do that work and then damage it both could be breaches of contract entitling you to cancel. But without seeing the contract it's impossible to say whether he had a right to remedy the situation after you notified him and then continue working under it. Most landscape contracts are for the "season" and you could have opened yourself up to liability for his lost profit. Take the contract to an attorney to review to be certain what your rights are, what your obligations to the landscaper are in case he screws up, and what the landscaper's rights and obligations are when he screws up. Getting the Village involved doesn't mean one thing or the other unless the landscaper was supposed to be licensed in town to do this kind of work.

I, too, am not certain what the village can do in this instance unless there was an encorachment of the edging on to the public way. You should make sure to take pictures of the damage before too much time goes by so your pictures reflect the damage that was caused as accurately as possible and not be subject to challenge. Additionally, a stopped check can be treated as a "bad check," simalarly to an NSF check, subjecting you to bank fees and potential civil/criminal liability. You should indeed contact an attorney
