'man grep'

DESCRIPTION
       Grep  searches the named input files (or standard input if
       no files are named, or the file name - is given) for lines
       containing a match to the given pattern.  By default, grep
       prints the matching lines.

And the pattern in this case is ^.i which says,

^ only match on the first character of the input
. match any single character after that 
i match the letter "i"

So it will find any lines that have any character in the first column and
the letter i in the second.   Look at the raw output of 'dpkg -l' to 
see what the letter "i" in the second column means.
