Yes, most of the XDR systems apply the use of artificial intelligence for different purposes. Similarly to EDRs, they use AI as a separate detection mechanism that allows them to detect especially sneaky threats. The feature of most artificial intelligences is that they can detect miserable signatures that are impossible to detect with the systems set up by a human. Generally, machine learning algorithms became more and more popular in anti-malware software.
Aside from the detection, XDR systems use AI to analyse cybersecurity incidents. Based on logs and the data from other event logging systems, extended detection and response systems can give the analysts a full picture of what is happening. Additionally, it may give advice on how to respond properly in that case.
