Have a look at :help :!. It says:
The command runs in a non-interactive shell connected
to a pipe (not a terminal). Use :terminal to run an
interactive shell connected to a terminal.
As top requires a terminal, it can't be run this way.
Running :!top in Vim works as expected, so :! seems to be implemented differently in neovim.

Is there a better way?
In Vim there are always too many ways. I'd do it like this:
" get result as List
let output = systemlist('myprog')
if v:shell_error
echoerr 'Command failed! Error message:' output[0]
else
" add output on top
call append(0, output)
" delete the rest
call deletebufline("%", len(output) + 1, "$")
" go to first ...

If you're going the Python + ps route, then this should be better and more efficient:
:pyx import os, subprocess
:let vim_cmdline = pyxeval("subprocess.check_output(['ps', '-p', str(os.getpid()), '-o', 'cmd='])")
Note that you're checking for the current PID (os.getpid()), since the Python interpreter is running inside the current Vim process.

Sadly, this is what I came up with.
Find the current process, the process parent, and use ps ax to obtain the path. Meant to work in mac. in Linux, it is easier with `/proc/XXX/cmdline'.
PY import vim
PY import os
PY pid=os.getpid()
PY kk=os.popen('ps -o ppid= -p ' + str(pid)).read()
PY kk=kk.replace('\n','')
PY tt=("let cmdline=system('ps ax | grep \""+...

If what you're looking for is a way to automate the sequence of commands (:silent grep and redraw!), then consider creating a new user-defined command for that operation.
(In fact, Vim documentation essentially recommends it for this particular use case with their NewGrep example.)
My recommendation would be:
command! -nargs=+ -complete=file Grep

I suppose by "open files" you mean active buffers (see :h windows-intro). That could be achieved with the command :ls a (use h-flag to get hidden buffers if needed).
To pack it into a function you could use a redirection or a dedicated getbufinfo() interface. For example
function! GetActiveBuffers()
let l:blist = getbufinfo({'bufloaded': 1, 'buflisted':...

Well, you need to do a redraw...per :h :!cmd...
This requires a hit-enter prompt, so that you can read any messages. To avoid this use :silent !{cmd}. The screen is not redrawn then....
But if you're simply looking to reduce the number of keys to press perhaps I can interest you in an 89% reduction of the second command. A single key combo...
