Oh dear, she sounds like a total PITA Yes, by law the hedge trimmings are yours so she is sticking to the letter (rather than the spirit) of the law in chucking them back to you.
Can I suggest you thank her hugely and intensely for throwing them back to you as you are using them to make a hibernaculum for the hedgehogs.
With any luck she'll be so jealous of you having hedgehogs (whether you have any or not ) that she'll keep them to make her own hibernaculum (for hedgehogs, not for her ).
Privet flowers are also a wonderful nectar source for beneficial insects, so you could always allow your hedge to grow up to say 7 or 8 feet tall so that it will flower and produce berries too. All in the name of wildlife too - she'd be 'hoist with her own petard' (love that saying ). You could put a sign up explaining
And keep smiling at her - she'll think she's missing something
