no. what they did is take the 40 year old engines and refurbish them (replace perishable seals etc), then add modern, western electronics and gimbal hardware and adjust for RP-1 rocket fuel rather than the 1970's Soviet equivalent.
whether they could actually produce new engines under the license they have is an open question - there has been a license for the RD-180 (used on the Atlas-V) for a long time, but no attempt at production has ever been made in the US. hell, they may not even be able to make new NK-33s in Russia, let alone the US - they were ordered to be scrapped and all the documentation destroyed - it was only due to a forward thinking (and brave) bureaucrat that they were warehoused and forgotten for 30 years...
these old Soviet design engines have very complex, tricky to reproduce metallurgy; that's why they are such good engines. but whether the formulas for that still exist.. who knows? they can certainly make new RD-180s in Russia, maybe the NK-33s use the same stuff, maybe not.
