Need to Write Shell Script based off of this shell command

Need to Write Shell Script based off of this shell command
I'm trying to read a bunch of log files and output the lines that contain particular strings.
To accomplish this, I've been running the following from the command line:
find . -name "*" | xargs grep "[tT] [hH] [iI] [sS]" | grep "[tT] [hH] [aA] [tT]" > output.txt
Two grep statements are needed in case I'm looking for a name that needs both first and last name.
I'd like to have a shell script that could do this, where I run the script from the command line and enter the strings as arguments at run time. My biggest question is how do I ensure in the variable that both lowercase and uppercase letters are searched for each letter.
I haven't written a shell script in a long time so I'm very rusty.
Thanks for any help.

zgrep
ZGREP(1) General Commands Manual ZGREP(1) NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
