Actuaries now face a design space that ranges from traditional rule-based automation to large language models (LLMs), retrieval-augmented generation (RAG), and multi-agent “agentic” systems that plan, retrieve, call tools, and reflect. This paper examines how these emerging architectures can support actuarial priorities such as transparency, auditability, and human-in-the-loop governance, with a focus on straight-through decision processes. To make these ideas concrete, we develop and analyze an agentic AI framework for straight-through underwriting of small commercial Business Owner Policies (BOPs) . We construct a synthetic but realistic experimental environment and compare three underwriting pipelines: (i) a single-LLM baseline, (ii) a naive RAG system, and (iii) a multi-agent “Agentic RAG” pipeline that combines targeted retrieval, third-party data checks, and explicit multi-step rule evaluation. The agentic system performs best overall, with the largest gains in multi-step and missing-information scenarios, where structured retrieval and reflection help the model avoid unsupported straight-through decisions.  \nKeywords: Retrieval-Augmented Generation (RAG); Human-AI Interactions; Synthetic Data Generation; Insurance Automation;  \n1 Introduction  \nArtificial intelligence (AI) has undergone rapid evolution in recent years, moving from rule-based automation toward models with increased adaptability and autonomy. Traditional automation systems execute predefined workflows, often lacking flexibility when confronted with unstructured or unforeseen data. In contrast, large language models (LLMs) such as those powered by transformer architectures have enabled richer capabilities: they can process unstructured natural language inputs, generate fluent text, and perform a variety of downstream tasks.  \nThe distinction between rule-based automation and LLM-based systems should not be interpreted too sharply. In many applications, explicit rules, statistical models, and LLMs often play complementary roles. A rule engine is well suited to apply known decision logic once the relevant facts are available. An LLM, by contrast, may be useful when those facts are embedded in messy business descriptions, underwriting notes, or other unstructured text. In some cases, LLMs may also help surface recurring patterns  \nor exceptions that can later be reviewed by domain experts and translated into explicit underwriting rules. The practical question is therefore not whether rules or LLMs are better, but how each can be used in the parts of the workflow where it is most reliable.  \nOne of the pivotal developments in this space is the technique known as retrievalaugmented generation (RAG) . In the foundational work by Lewis et al. (2020), RAG models are defined as combining a parametric memory with a non-parametric retrieval mechanism. The authors show that such a hybrid architecture improves performance on knowledge-intensive tasks by enabling the system to access external factual content rather than relying solely on internal model parameters. Subsequent surveys and reviews reinforce that RAG architectures help mitigate phenomena like “hallucination” (where the model asserts facts not grounded in the external world) and improve factuality and traceability (Gupta et al. , 2024) .  \nWhile RAG enhances knowledge access, it remains a relatively narrow paradigm: retrieval plus generation. The next frontier is what many authors term “agentic AI,”which are systems that behave more like autonomous agents, capable of setting
