We're about to fly a spacecraft into the Sun
> And I'm not aware of any KSP mod that helps you plan slingshots
If you're willing to go for the full n-body package, Principia [0] has a pretty nice flight planner that is quite usable for planning more complicated missions.
KSP Trajectory Optimization Tool [1] is a non-mod alternative with some additional capabilities beyond flight planning as well. I think this one is designed for stock gravity so it should be usable in an otherwise vanilla install.

A rudimentary simulation of the three-body problem
Principia is extremely impressive, they document all their math here: https://github.com/mockingbirdnest/Principia/tree/master/doc...
One interesting detail is that the source code makes extensive use of non-ASCII identifiers, for mathematical symbols and for the names of mathematicians. One of the two primary contributors is also an active contributor to Unicode

Eli5, Why are planets orbits elliptical and not circular?
But one should just be aware that KSP simplifies by only tracking the strongest source of gravity. This turns all orbits into actual ellipses. But there is a mod called Principia that replaces it with the proper thing, thus allowing for very chaotic (but cool) flight paths using less thrust.

Is there a mod in KSP that replaces the Maneuver node tool and makes you do real orbital mechanics?
Principia has n-body

Just a friendly PSA that kerbal space program is free on the epic game store this week. Build rockets and figure out how to get to space!
Install Principia and Real Solar System, then try again :P

Theres a mod that changes that to N-body simulation, it's called Principia
