I can see you've provided a detailed crash report for your Minecraft 1.7.10 modding issue.
Based on the crash report you provided, I can identify the exact cause of your Minecraft crash. The issue is clear from the error messages:

Root Cause Analysis
The crash is caused by a corrupted CodeChickenLib mod file. Here are the key error indicators:
ZipException: java.util.zip.ZipException: error in opening zip file for CodeChickenLib-1.7.10-1.1.3.127-universal.jar
Failed to read properly: Zip file CodeChickenLib-1.7.10-1.1.3.127-universal.jar failed to read properly, it will be ignored
Missing class: java.lang.NoClassDefFoundError: codechicken/lib/packet/PacketCustom$ICustomPacketHandler

The Problem
CodeChickenLib is a foundational library that many mods depend on, including:
ThutTech (part of Thut's mods)
McMultipart
ForgeMultipart
thutcore
ThutConcrete
When this library file is corrupted, all dependent mods fail to load, causing the game to crash during the mod initialization phase.

Solution
You need to reinstall the CodeChickenLib mod. Here's how:
Download a fresh copy of CodeChickenLib-1.7.10-1.1.3.127-universal.jar from a reliable source like:

CurseForge
Modrinth

Replace the corrupted file in your mods folder with the new download
Verify the file integrity - the new file should be approximately 1.2MB and should open without errors
Restart Minecraft - the game should now load properly with all your mods

Prevention
To avoid this issue in the future:
Always download mods from official sources
Verify file downloads are complete before moving them to your mods folder
Consider using a mod manager like MultiMC or GDLauncher for better mod management
The crash should be resolved once you replace the corrupted CodeChickenLib file with a fresh copy.

As far as I can tell with my own testing, its fully incompatible with CodeChickenCore unofficial, which bundles codechickenlib
