No. The l: is required only if you want a local variable with
the same name as a Vim v: variable (however, it seems that
even then the l: is not always needed). See ':help l:var'.
The following shows typical usage where l: is not needed:
let g1 = 'global value'
function! Try()
let l1 = g:g1 " g1 is error E121: Undefined variable: g1
let g1 = 'local value'
let g:g1 = 'locally set value'
$put =l1 .' '. g1 .' '. g:g1
endfunction
Sourcing the above and entering ':call Try()' gives:
global value local value locally set value
