📄 Description

Summary

Fixes #841

Four apps in llm_apps_with_memory_tutorials accessed response.choices[0].message.content without verifying that choices is non-empty and content is not None. This is the same class of bug fixed in PR #820 (DeepSeek) and PR #840 (beifong).

Affected files:

ai_arxiv_agent_memory/ai_arxiv_agent_memory.py — arXiv paper search with GPT-4o-mini
ai_travel_agent_memory/travel_agent_memory.py — travel agent with OpenAI
llm_app_personalized_memory/llm_app_memory.py — personalized memory app
multi_llm_memory/multi_llm_memory.py — multi-LLM app (OpenAI GPT-4o and Claude Sonnet)

Root cause: An empty choices list or None content can occur when a content filter is triggered, a quota is exceeded, or a transient API error occurs.

Fix: Add an explicit guard before each choices[0] access in all four files. The ValueError propagates cleanly to any surrounding error handling.

Test plan

Normal API responses continue to work correctly
ValueError is raised when choices is empty or content is None
