Have you tried revaluation for any of your IELTS attempts? If you're 0.5 short on Writing/Speaking in one of those attempts, there is a good chance that might go up and your CRS score along with it.
At 402, you're certainly eligible for OOPNP provided you have at least a Canadian Bachelors or an ECA indicating the same. If that is the case, you should definitely consider recreating the profile over the weekend (wait to see if there is a draw this weekend before recreating your profile, I don't expect CRS cutoff to fall to 402 but why risk that) so that you're eligible for OOPNP. OOPNP is a bit far gone into their process already - members have started receiving acknowledgments to their submitted applications - but there can be no harm in trying to get your profile in the OOPNP consideration set even at this point in time. Unfortunately, being eligible and showing interest (by recreating the profile on or after 1st June and selecting 'Ontario' or 'All provinces and territories') is the max you can do in terms of applying for OOPNP. Selecting you by sending you an invitation (PT) is entirely their call.
You can create an EE profile entirely on your own without your lawyers' assistance as well. It's a fairly simple task and there is a complete thread with step-by-step instructions to do the same. Maybe you can try creating a profile yourselves and after you've successfully done that, you ask your lawyers to withdraw the old profile - keeping more than one active profile for the same PA is redundant and possible grounds of misrepresentation.
As for kicking your lawyers, entirely your judgment but (with some of them at least) you'll have a hard time figuring out which end is the butt.
All the best!
