I'm looking for software that can provide detailed insights on my codebase, specifically regarding the function calls. I'd like it to answer questions like: "Show me every function that invokes lodash.get(), what data flows into it, whether those callers are reachable, and what the impact would be if I changed it." Is there any tool available that can do this with absolute accuracy? Please share your suggestions if you have any!

You're not likely to find any solutions that promise absolute accuracy because of the complexities involved with dynamic languages like JavaScript. Tools can identify calls and dependencies, but they can't get every nuance. Static analysis offers decent reliability, but more often than not, manual reviews are necessary.
Why not create a custom script to search your project for this? You could filter through the data flow and assess the impact based on your specific criteria. This way, you'd have a level of control over the analysis you need.
The issue here is related to the halting problem; with dynamic languages, achieving complete accuracy is a challenge. While tools can walk through your code's structure, they may miss certain call scenarios. Just remember, while we aim for clarity, no tool is infallible.
Honestly, most IDEs can help you locate where lodash.get() is used. However, for 100% certainty, no software really gets it perfect. You might have to dive deeper with static code analysis tools that provide high accuracy, but they can't guarantee complete correctness under all conditions.
