I read somewhere on HN in the last couple months that Google is prone to banning/deleting accounts that it thinks are associated with accounts it bans, so I would not do this.
I even recall an article where the google developer account of a company was blocked because it got associated with the personal account of one of their old employees.
I think Google allows 3-4 accounts since it's common for families to all use Gmail, so they're lenient in that regard. Obviously, creating 10 accounts with 10 Twilio numbers would arouse suspicion and those accounts would be swiftly banned.
Multiple accounts are allowed, sure. That's not the issue.
The issue is trying to use multiple accounts as a kind of loss mitigation strategy. If Google knows about your multiple accounts, and one of them gets banned, they're _all_ at risk of getting banned just for being associated with the one.
