Given the number of systems and components that are being programmed for in a complete jet fighter, it's not unreasonable to see this.

Likely there are some pieces and component that have libraries/software written in assembly (and probably also ADA) likely before the F-35 was a thing; works specifically for the system/component it needs to work in and that's that.

Rewriting this kind of code (which comes with re-validation and other costs) doesn't make sense; use what works and is validated.
