I can confirm I get this also, using st (suckless/simple terminal). I have a VPN
script in my net.eno1 script, so the output might differ  slightly  from  yours,
although the strange behaviour seems the same.

I suspect that this is  just  a  silly  bug  in  which  a  prompt  is  displayed
prematurely, and since the shell has  already  dispatched  the  $PS1,  it  waits
until <RETURN> is received before showing it again, as it thinks you're  in  the
process of typing a command.  As the "Starting openvpn ..." text is  printed  to
stdout, when you press enter, it assumes an empty command has been  entered  and
does nothing but display another prompt.

As a simple demonstration, see what happens when I type a command  `echo  Hello`
before pressing enter:

[super] root@ad-gentoo-main / # etc/init.d/net.eno1 restart
        <... TRIM OUTPUT ...>
[super] root@ad-gentoo-main / #  * Starting openvpn ...                   [ ok ]
 * WARNING: openvpn has started, but is inactive
 * Mounting network filesystems ...                                       [ ok ]
echo Hello
Hello
        <RETURN PRESSED.>
[super] root@ad-gentoo-main / #
