'Of course you didn't. Father hired a Seer. A woman killed that guard, a servant of the Rope's. The Seer was terrified and didn't even stay to be paid! Now get off me, thief.'
The Seer here was just that and nothing more, but the word "seer" has meaning inside the story, in that way that SE uses words repeatedly in association with certain characters.

She knew that the boy would have to die, yet something within her seemed to be fighting that conclusion, and it was a part of her she could not recognize. She'd been taken, born a killer two years ago on a coastal road. The body she dwelt within was convenient, suitably unmarred by the events of a dramatic life – a young girl's body, a young girl whose mind was no match for the power that overwhelmed it, obliterated it.
But was it obliterated? What had the coin touched inside her? And whose voice was this that spoke with such power and determination in her head? It had come upon her before, when Whiskeyjack had uttered the word Seer.
She tried hard to remember any dealings she might have had with a seer in the last two years, but none came to mind.

The girl surprised them both by replying in Daru, 'I understand you,' she said haltingly. 'More now. You're not Malazan, you're not speaking Malazan. But I understand you.' She frowned. 'How?'
'Malazan, huh?' Coll said. 'Where are you from, girl?'
She thought for a moment. 'Itko Kan,' she said.
'What the hell?' Coll laughed. 'What storm blew you here?'
Realization flooded her eyes. 'Where's my father? What happened to the nets? I bought the twine, and there was that Seer – Riggalai the Seer, the wax-witch. I remember her – she died!' The girl fell to her knees. 'She died. And then—'
Coil's expression was severe, thoughtful. 'And then?'
'I don't remember,' the girl whispered, looking down at her hands. 'I don't remember anything more.' She began to cry.
The word, when referring to The Pannion Seer, triggers Sorry's memories, so its meant to jump out at you when you see it too. Long story short, tho, yeah that seer Challice mentions is only essentially important in the context she uses it.
