There's a couple of options that have worked for me:
1. You can manually create the parameter on the node and ensure it has a Run Time Property Name of ls.brain.node.csv.unescapedQuoteHandling
You can enter one of the following values:
Error
Skip Value
Stop at Closing Quote
Stop at Delimiter
2. Enter a value in the EscapeCharacter property that is very unlikely to ever be in your file. I usually enter something like ÷ which is generally safe to assume you'll never see it in a file you're receiving.
