It’s not much more difficult to design and build a turbofan than a turbojet. A turbofan is a development of a turbojet - the operating principles and requirements are the same.
What makes things difficult is how you increase performance, and the fine controls needed to manufacture for very high reliability. As engines have pushed the limits of deign for ever greater performance, so there has been a quest for exotic materials, complicated production techniques and fine tolerances.
Take the compressor blades. These began as machined items, but would creep (lengthen under load) due to metal grain structure, so an improvement was to manufacture to encourage long, thin crystals with fewer boundaries. Eventually this wasn’t enough, so single crystal blades which are grown rather then machined were developed. This allowed performance to be raised, but is difficult and very expensive. This approach is common to turbofans and turbojets.
Modern turbine blades operate continuously in air which exceeds their melting temperature and require a carefully designed air system to wrap them in a jacket of cooler air so they don’t melt - this isn’t a prerequisite for an engine, but it is required to increase the performance. This development isn’t limited to turbofans or turbojets, it happens in both to squeeze more performance out of more or less the same materials and same basic design.
In essence, building an engine isn’t the hard bit - building a very good engine is very hard.
