############################################################################### <# .SYNOPSIS Evaluates source files for refactoring eligibility using LLM analysis. .DESCRIPTION Uses Language Learning Model (LLM) analysis to determine if a source code file should be selected for refactoring based on specified criteria. The function processes the file content through an LLM query and returns a boolean response. .LICENSE Copyright (C) 2026 René Vaessen / GenXdev This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
