I am sorry to report that neither Anticybersquatting Consumer Protection Act 15 U.S.C. § 1125(d) or the ICANN Domain Name Dispute procedure (UDRP) will be of any use to you since you have no rights that pre-date the domain name registration and the domain name holder clearly could not have had knowledge of you at the time he registered the domain name. Also, company names are not trademarks unless used as such so the mere registration of an LLC with your state corporation agency would not give you any rights in the name as a trademark. In fact, there are 100 federal trademark registrations or pending applicaitions of which the letters "KD" form all or part of the trademark including at least one for "Entertainment services" (I have assumed that "productions" involves services of this type) so that I suggest that you find another name, especially if you want the name of your company to be the domain name of your website.
