It's probably best to use ListView instead of ItemsControl for a potentially long list of messages due to virtualization.

"Agentic" is not a good feature or domain name because it's an adjective. If what you're building is a Chat, name it "Chat" (or "AI Chat"). Having just the word "Agentic" as the domain name is confusing because it could mean multiple things and it forces us to dig into the content to understand that this is actually a chat bot.
