Sorry, you are perfectly right. The code is
(gud-basic-call "script --language python -- print('Gud initialized')")
(gud-basic-call "script --language python -- print('Gud initialized.')"))
so you are actually sending two slightly different commands.

Just after the stop. Transcript (with line numbers for reference):
01|(lldb) b exec_byte_code
02|Breakpoint 2: where = emacs`exec_byte_code + 20 at bytecode.c:476:33,
address = 0x000000010b389b84
03|(lldb) c
04|Process 13507 resuming
05|(lldb) emacs was compiled with optimization - stepping may behave oddly;
variables may not be available.
06|(lldb) Process 13507 stopped
07|* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 2.1
08| gud-info: (gud-lldb-stop :file ////Users/mattias/emacs/src/bytecode.c///
:line 476 :column 33)
09|Target 0: (emacs) stopped.
10|(lldb) <cursor here>
In lines 5 and 6, an (lldb) prompt is printed although no input takes place
there. No such prompts are seen when lldb runs in a terminal.
Line 6 also prefixes "Process" with an extra space which isn't present when
running in a terminal either.

Overkill is the least of it. Just you wait until someone makes you debug some
crafted source code that causes your Emacs to evaluate arbitrary Lisp
expressions!
In general:
1. Don't use `eval` for parsing data.
2. Don't use `eval`.
