Yes, but Claude Cowork isn't just an LLM. It's a sophisticated harness wrapped around the LLM (Opus 4.5, for example). The harness does a ton of work to keep the number of tokens sent and received low, as well as the context preserved between calls low. This applies to other coding agents to varying extents as well.

Asking for the trace is likely to involve the LLM just telling the harness to call some tools. Such as calling the Bash tool with grep to find the line numbers in the trace file for the command. It can do this repeatedly until the LLM thinks it found the right block. Then those line numbers are passed to the Read tool (by the harness) to get the command(s), and finally the output of that read is added to the response by the harness.

The LLM doesn't get a chance to reinterpret or hallucinate until it says it is very sorry for what happened. Also, when it originally wrote (hallucinated?) the commands was when it made an oopsy.
